The problem I have is not my Mac, it is the poor quality of my internet connection. Games like WoW and Drakensang Online, don't work because the programme crashes. Some of the simpler games work, like Villagers and Heroes, but that is really a kiddies game.
Dunno how bad internet connection crashes WoW. I know those in AU/NZ had extremely poor connection (1k+ ms) yet they still managed till recently when they finally got a data center. Sweden has one of the best Internet, I thought. Unless, of course you're on dial-up then well, yeah...online games may not be such a good idea. >.< Might be a good idea to gander at your ISP's help desk to figure out a solution.
