First and foremost the Cepheus Engine like the game it tries to emulate, Traveller, are science fiction roleplaying games. But instead of being limited to just sci-fi adventure stories, could Cepheus handle games in other genres? While thinking about what kind of games I could run with Cepheus Light, I wondered if the CE would actually work as a multi-genre roleplaying system.
Historical and pseudo-historical games are very easily done using the Cepheus System. The game assumes that the various worlds the player characters travel to have different tech levels from 0 (Stone Age) to 15 and beyond. The modern world is about tech level 8. The game also lists weapons, armor and equipment suitable for a variety of tech levels. So the CE is already designed with various levels of technology in mind.
The only problem I see are the CE careers which have been tailored to fit the implied setting. Retirement rewards like space ships, or certain skills might be inappropriate in a game set into medieval times for example. But if you use an alternate character creation method like the one I mentioned in my last post, things should work out quite nicely. It should also be quite possible to hack the existing careers into something more fitting to the kind of game you want to run. More adventurous referees might even want to design their own careers.
If you add fantastical elements to the game, things get a bit more complicated. The Cepheus Engine does not have a magic system out of the box. You could just use psionics and call it magic, or you could try to adapt an existing magic system from a fantasy roleplaying game. I haven’t actually tried it yet, but I guess you could just take the magic system from an old edition of D&D and use it with Traveller.
Alternatively you could just wait for the release of Sword of Cepheus, a sword & sorcery version of the Cepheus System. Omer Golan-Joel from Stellagama Publishing is currently working on that one. This project actually made me think about the CE as a multi-genre game in the first place.
So why should anyone actually want to use the Cepheus Engine for anything else than what it was designed for? First and foremost CE is a simple, easy to learn roleplaying game. If you are already comfortable with the system, you could easily run/play games in other genres without relearning everything. The CE is also pretty robust. You can hack it easily without fearing to break everything. Of course Traveller or the Cepheus Engine are not the only games you can hack to run in other genres. But if you like the 2d6 mechanics but want to run a non-scifi game, the Cepheus Engine might still be a valid choice.
