It all depends on how active the games are. If not many people play the game then its going to be denied. I've never played them games so this doesnt really affect me.
Only the most popular games get their own forums, diablo two is fun and all but most people here are either RS or have upgraded to WoW. Diablo 2 has it's own forums all over the web I see no point in cluttering up sythe with yet another forum =/
