Church is alright, i mean it brings the people in (that is, when im not there to get them ragin') i mean who doesnt want to get locked up in a room/building with a bunch of claustrophobic players? Honestly...
Lest' we not forget other maps such as Snuggles, good every now and then gets them joining and running.
But its not my right to make the decision only to suggest them, so im sure you'll add good maps, possibly maps better than the one i suggested. All and all, its all about having fun.
