Runescape. It was okay, but the user base was generally pretty terrible (and probably still is). Since then, tried these:
Maple Story: Didn't like it. Thought the controls were awkward, and didn't really pursue it
World of Warcraft: Good. Still play it off and on once in a while, but I'm not very good at PvP. Raiding gets repetitive unless you play multiple classes.
City of Heroes/Villains: Okay, but only played the trial. Wasn't bad, but there wasn't much variety (only 5 classes, but lots of visual differences which I do like)
Champions Online: Good. Didn't reach end-game levels, but I did some leveling and group stuff and it was fun. Involved more player input than most MMOs.
Fallen Earth: Did the tutorial, didn't like it. Lagged horrendously, and didn't like the game mechanics. Might've improved since, but I wouldn't know.
Tabula Rasa: Tried a trial, didn't really get into it but it felt pretty solid.
Final Fantasy XI: Like the classes, but the game's too slow and the interface and controls are bad. Would love a version that cloned WoW.
Wanted to try out FFXIV, but I haven't heard anything good about it at all. And DC Universe online comes out in two days, so I want to try that as well
