Well for me I want to go to the forum where people are actually working on the game. If you look at any other forum on the net right now, with the exception of simple skin mods, nobody is actively trying to mod the game. Many of the members here did the original boss mods, ect, so it just makes sense to work on this sort of thing here.
Don't take that the wrong way btw... the skin mods are fantastic, but we already know how to do that.... I want to learn how to do other stuff.
