Recommend me some PC games

It's the best MMORPG out there, but after being hooked on Maple for two years, I am a little hesitant to try an MMO that has been described to me as a "crack cocaine delivery system." I want something that I can put down on a moment's notice and I think WoW is a bit hardcore for what I am looking for.

I think you should wait for Brood war then. Star craft was the 1st MMO I ever played (before I started playing Maple), and damn... did I have some fun playing UMS player made maps.
