Magic World Online~
mwo.enjoymmo.com Official MWO Website
Deeper gaming then you've ever experienced, Ive played MMO's for 7+ years, started with EQ and Diablo 2XP, then went to Guildwars and then a bunch of Free MMO's ie Shaiya, RF Online, etc... MWO has graphics that wont overtake your computer and it has a built in robot so you can still be playing even when your not actually at your computer. The depth of the game makes the Robot a must, it's free to download, free for life to play and could be just what you're looking for, it was for me~
