I'm sorry to say that you argument's weak. The whole purpose of this Community is to discuss everything regarding the Devil May Cry Universe and meet people who share our thoughts about the game, or witness interesting theories and news about new Devil May Cry Projects.
However it is still a forum and it needs a place like this one where members can discuss new ideas regarding the forum or ask questions about it.
Since Devil May Cry is a game, it means that all of us here (if not only most of us) are gamers. Therefore the General Gaming Discussion is a nice little add.
As for General Discussion it exists only because even the most passionate Devil May Cry Fan would still need to discuss and read other things in the boards. But don't get it wrong. General Discussion is not crucial to the Devil May Cry Community (It is, but not as much as the other DMC-related Forums) as the Community was created to discuss about Devil May Cry.
The idea is not bad, but it is not suited for this place. This Devil May Cry Community is not the answer of all the problems or something as noble as that. It's just one of the best DMC Forums out there, and the people who enter it and create accounts in it, do it because they share our Devil May Cry passion, not to seek solutions about their problems. There are other forums for that stuff.
I hope this matter is at an end.
