This is a great website, but, there are already websites out there dedicated to their respective games, which makes it a hard sell to get anyone new to join. If I were looking for information for another fighter, I'd go to their main website which will undoubtedly contain the best/most information. Huge chunks of what was on AstralHeat seemed to have been directly copy/pasted from DustLoop, which doesn't serve any purpose as the information was already on DustLoop in the first place.
You'll also end up cluttering up this site with a bunch of games/information that not everyone cares about. If you include Tekken information, you'll end up bugging those of us who don't play Tekken for example. Now, if you could set up some sort of filtering by game to weed out one's that you aren't interested in, then that would be great :)
If you look at SRK, they don't generally set up massive forum setups for games that there are already established communities for. Like for Blazblue, they didn't set up a ton of subforums for each character, but, just made one big disorganized mess of a thread for each character (whether that's better than having a bunch of mostly empty sub-forums is debatable). I do like their general fighting game forum though, lots of very little known games (at least, one's I've never heard of) get discussed there.
Whatever you decide to do, don't ruin the best Soul Calibur website :)
