The LAST thing you want to do is have too many different forums. That can kill a site.

Sure having a single one for each individual game is fine - But don't go all out and have individual forums for SP COD, MP COD and all that type of shit.

Expansions for games don't need their own forum either....IMO, you should have forums:

OFFTOPIC
SIG/INTRODUCE YOURSELF
Possibly a GENERAL/NEWS forum as well.

and then, forums for individual games.....
MOHAA
COD
DOD
BF1942
and so on....

That's all you need - Don't bother with forums like OTHER GAMES, SPORTS GAMES and all that shit - It can all be covered in an OFFTOPIC forum.
