Although predominantly a Fantasy/Sci-fi gaming club there are quite a few members who play Ancients/Medieval periods as well. Best thing to do is join the forum (it is restricted access due to the massive amounts of spam we were getting) and have a chat. Failing that just drop in on a Sunday evening and have a look around.

Yes its fair to say War & Conquest is the most played Ancient set there, plus the occassional bit of Saga and World War One/Wings of War.
