Ive only played Warhammer and Lotro but out of those overall, I liked lotro, theres alot to do in game whereas in warhammer its pretty much PVP or Public Quests otherwise you will want to spill yourself on the keyboard.
Well I don't remember the title of the game. But there is one that i remember that is exactly like runescape. Even down to the first quest in which you catch and cook shrimps<--unnessiary "s"
