I am seeing 3 games by Blizzard Entertainment on the index, I think that it might be better to make each of them sub-forums in a New Blizzard Games section where WoW is at right now.
Blizzard Games: (StarCraft2 to be added when it comes out)
World of Warcraft (Market Sub)
Warcraft 3 (DOTA)
Diablo 2 (Classic And Expansion Market Subs)
Something like this, have it down the way you admins want it if you think that this is a good idea.
