time-travelRecently I finished running a TimeWatch adventure. Over three sessions (roughly 10 hours in all) in real-time with events spanning centuries it taught me a lot about writing and running a time travel game. What follows are some observations that could help others accepting the challenge of attempting a similar task.


In the process of writing the adventure each Scene would produce numerous events that I realised would have to be catalogued. The TimeWatch agents have the ability to visit those events in any order so it is important that the GM be able to quickly reference them and get an idea of what happens when.

You might notice that events cluster around particular time periods. This can highlight where to focus your research, sprinkling scenes with era specific music, fashion and cultural references.

Linked to this is making sure you know the entire history of any important NPCs in your adventure. PCs might meet a character in one particular point of their life and want to use their tether to find out what happens to them in the future. You’ll want to keep track of when those same characters might cross the PCs paths in the future or if the influence of the TimeWatch agents put their lives on a new course.


Nothing slows an adventure down more than the GM struggling to come up with something interesting during play. Prepare for anything that you know is going to happen during the game and as many eventualities as you can think of. If you don’t end up using it that material can still be used for future games so it is still worthwhile.

I created a list of possible Time Chases, specifically linked to the alterations in the timeline. Not only does it make it easier to pull these out when you need to it helps reinforce what the new version of history is like. While it is background details it still makes it memorable.

I’d created another group of TimeWatch agents, carrying out a parallel mission to the PCs. I introduced the members of this other team as they passed each other on the way from the briefing rooms in the Citadel. My intention was that should the PCs get into trouble or miss any important avenues of investigation this other group could help.

Not that I’d make it easy for them. I’d sketched out possible fates for each member of the other team, getting the worst of the changes in time. In order to get their help the PCs would have to rescue members from being stranded in the ancient past, insane asylums in the 18th century or death at the hands of terrorists.

In the end the PCs didn’t need any help so the other team remained in the background, solving minor problems so the heroes could concentrate on the important parts of the investigation. Yet I don’t regret the time spent as it helped flesh out both TimeWatch and those who work alongside the PCs.


It isn’t possible to know everything and no matter how much research you do there are going to be times when you need to find out more information to develop the setting. This is especially true in TimeWatch where the PCs can investigate any clue at any point in history.

One of the important locations in my adventure was a small island off the coast of Greece. The PCs could investigate it at any time and they choose the year 1950. Within a few minutes I was able to bring up some details about the country during that period and give the players a feel for the place.

Obviously this requires having access to the internet but in our modern age that isn’t too much of a problem.


Just like the clothes shop in ‘The Time Machine’ or Hill Valley in ‘Back to The Future’ places can act as both an oasis of stability and reflect the passage (or alteration) of time.

In our adventure the PCs became very fond of the Red King hotel in New York. Investigating a murder there in 21st century they got to know the manager. Travelling back to the 1970s they decided to stay at the hotel, meeting the manager when he was just a bell boy. Later they travelled into a post-apocalyptic future where the hotel crumbled and decayed around them the further they went. Finally they went back to the 1950s when the hotel was first built.

When ever they needed to stay in a particular time period the Red King was they immediately wanted to go. Being able to describe the current state of the building and the staff helped establish the particular period they were in and emphasise that the TimeWatch agents were exploring more than any mortal could in a single lifetime, their own lives interweaving with the history of the hotel.

Familiarity can also come into play when the PCs try to solve the problem. It helps if you establish each location with a clear identity and purpose. If the players can understand its function then they can use it to help them.

At the conclusion of the game the PCs knew exactly where to get everything they needed to fix time based on their prior experience with the variety of locations they’d encountered.


During the game it helps to bring a scene to life with minor details, whether it be the music playing in the background of a bar, the sound of bird song in the woods or a couple arguing loudly on the sidewalk. As long as the trivial doesn’t distract from the important details it can help reinforce that the PCs are living in a particular moment and not just moving between plot points.

If the TimeWatch agents revisit these events then these minor details can be useful temporal landmarks. ‘Groundhog Day’ is a good example of this, with the first run through establishing the trivial events that Phil Connors must live through each day. Encountering one such event again the PCs will know what is going to happen next.

At any given moment PCs or other time travellers could be behind the scenes, engineering those moments or taking advantage of them. This can lead deeper significance to these details or put them in a new perspective.

During the adventure the PCs were speaking to a college professor outside just before he went cycling. I briefly interrupted their questioning of the professor by mentioning that there was screech of tires at the end of the street. There had been a near collision between to vehicles and the drivers were shouting at each other before they drove away.

It was a minor detail, maybe just hinting that if they hadn’t stopped the professor he might have been involved in that near collision. The adventure proceeded until later when one of the PCs wanted to slip a note containing vital information to their earlier selves.

The near collision became the perfect distraction to cross her own timeline. While everyone was looking at the cars the PC slipped the note into one of her teammates pockets and vanished before they saw her. A throw away detail had become an important plot point.


With time travel PCs can spend a lot of time devoted to their investigation. They can spend months or years befriending NPCs or infiltrating organisations. During the adventure this happened several times with several PCs enrolling as students at MIT or taking a job at a zoo so they could eventually steal an exhibit.

You probably won’t want to run through this periods in detail but spend some time mentioning the people they encounter or things that might happen to them reinforces the idea that this is a long period of time for the PCs, if not the players.

They might have a simple goal but come away with new friends, ex-girlfriends and funny stories to tell about the 7 months they spent in an art commune or working as a vet. These additions to their own personal history could lead to further adventures down the line.


There are likely to be multiple routes of investigation that PCs can follow. The trouble can be that even when they have all the pieces of the puzzle they might worry that they need to explore the paths not taken before they can solve the problem.

Depending on how long you want to run an adventure you could let them continue investigating, maybe coming across the some of the same clues to hint that they are retreading old ground. This could, however, make things drag out longer than they need to be.

You can reassure the players by confirming what their PCs know. In certain circumstances the PCs, as TimeWatch agents, will be more experienced and know more about time travel than their players. There is no harm in telling a player that their character is confident they know what is going on and that they can now deal with it.

This leaves the players free to concentrate on coming up with a plan.


The GM has a lot of things to remember. Not only must you keep the plot straight in your head you have to be able to narrate what is happening and react to anything the PCs decide to do. Amongst all of that it can be easy to forget to reward them with Stitches.

I was guilty of this and once it was pointed out attempted to give them out when ever possible (especially as the plot reached its conclusion and they need all the help they could get). One way to get around this is to encourage the players to award the Stitches, helping share the responsibility.



  1. This is great! I’m so looking forward to running Timewatch with my group, but am waiting for the books to be done, just because we already have so much in the queue.

    But these are great items and I’m looking forward to trying them out and reporting back.

    You created your own scenario, I assume. How easy was that to put together?

  2. Glad you liked it.

    Hopefully you’ve seen the TimeWatch scenarios also on this site, which will give you an idea about how I go about writing them.

    I try to make the source of the change to history not immediately apparent, since once the PCs work out where it is all they need to do is get there and prevent it.

    For example in ‘Stop Me If You’ve Heard This Before’ a time traveller receives a virus that makes people laugh in 1962 and releases it in 1974 but the virus originates in 1518.

    In ‘The Buffalo, The Pirate And The Consulting Detective’ history changes in 1887 due to the activities of Captain Kidd in the 17th century.

    Finally ‘Nevermore’ alters the outcome of WWII due to Edgar Allen Poe not writing ‘The Gold-Bug’.

    In the scenario I ran for this group I did something similar, with very obvious changes but the source of these alterations needed serious investigation, with the group jumping up and down the 20th century.

    I think once you have your core idea, the thing that has caused the change, you’ll have a rough idea about the time periods involved that can help you concentrate your research. You can pick out important historical figures who might be fun to include or historical events that will serve as a good backdrop to the adventure.

    It is important not to forget that it is a game. I’ve rewritten sections which would be realistic but dull. For example initially some important information would be given at government secret meetings held behind closed doors.

    While it could be fun for the PCs to try to get around the security I shifted a lot of that important exposition to a gathering of a secret society consisting of the elite of society held on a private island. PCs now could don masks to blend in or pose as servants.

    The length of the game you want to run can also determine how much you include. An adventure can be straightforward, with every clue leading to the next until the investigation is complete.

    Since I wanted to make quite a lengthy game I didn’t make things too straight forward. There were some false leads, mainly because the alteration to history had created changes that had nothing to do with the perpetrators ultimate goals. This led the PCs to suspect the wrong factions were at work, which none the less led to interesting confrontations.

    If the adventure is taking too long you can always cut material.

    Once you start formalising the timeline and are satisfied that it all holds together I think you have the confidence to run an adventure which by its very nature could occur in non-chronological order.

    Hope this helps.
