Battletech? If you wanna get back into it look up megamek. It is so fun.
Faaaack no. I mean like old avalon hill wargames, with the hex based cardboard maps, usually in two or three huge sections, and tiny cardboard chits. 'The Battle of the Bulge'. 'Blitzkrieg', 'Afrika Korps' etc.
I don't like science fiction AT ALL. No star wars, star trek, any of that shit. Just wargames and I used to play MUME. And GTA occasionally.
