Is adding WoW to my Games list in Steam, launching WoW from Steam, and using Steam's in-game interface allowed? I don't want to use it and then find out you can get banned for it.
You can add any custom game the Steam Launcher. You just have to manually point to the game executable. Pretty handy. Steam is taking over the gaming, dontchaknow?
Ah, I see. I've used it only for Orange Box games up until now.
