This is a thread for letting people know what type of PBP games you would like to play in (as opposed to PBP games you would like to run). The theroy here is if someone is perhaps thinking of running Game X, but perhaps is hesitant because they think no one would want to play said game, such a thread might give them a better idea of whether or not running Game X would be viable.
Of course, just because a lot of people may want to play Game X doesn't actually obligate anyone else to actually run it. But perhaps seeing enough interest might inspire someone to do so...
