A forum on people's tactics would be nice... for example a bunch of people just abandoned some cities, which are by now re-occupied, but I'd like to ask them why they did that (are they seeing something I'm not?). There's no good place to pose questions like that now.

Well, the Alliances/Trashtalk sorta goes for everything right now.

HOWEVER, there is www.gewarriors.com where we have a forum TITLED Game Tactics. I'm sure you can ask your questions there.

Either what HLU said or put it in the General GEWar forum :)
