Meh. If I remember S4 leauge didn't require a fast interwebs and was really fun. Though if I also remember correctly community was kinda /yawn.
Also I hated Atlantica, Maplestory (>.>') /yawn, and DFO, I got to 30, got bored of dungeons, tried PvP, got bored of that really fast, seemed really repeditive. Runescape? z,z No comment. (Has a level 94 z,z OwnerMagix) You could also try some of Alaplaya's games... Perhaps Luna Online. I played that for a while. Was okay. Also I remember Battle of Immortals was addicting as heck in Closed Beta, got mad though cuz' my CBT characters got deleted z,z so I stopped playing.
