You can basically implement any game in TS, and users do that indeed. You can download those in the Workshop. I for once use TS to playtest my own game (built it myself) as well as fan cards, simply because i don't have anybody to do that on a regular basis in real life.
So, Kuildeous, in case you fancy a game or two, might i PM you my Steam thingy? This goes for anybody interested, not only Kuildeous.
