if your willing to pay a monthly fee ($12 or $15 depending on how you pay)get world of warcraft, if not and you still want a good MMO, get the guild wars games. Dark Crusade and age of empires 3 are pretty good, though IMO, not quite as good as the command and conquer games. If you want a good strategy game get one of the battle for middle earth games (theyre made by the same teem as generals), the first one if you care about the campaign mode and overall single player experience, the second if you mainly want to play online and scrimmage.
