I COMPLETELY Understand you. And I will tell you 1 thing. There is NO game in this world that will make you quit IF you're playing it with 1 or more friend.The friend you're playing with can be from onrpg or school etc...
But mark words DricerX, If you're playing with 1+ friend, you will look foward to leveling because you will want to compete with your friend(s), or you will want to go to high maps, or kill a boss together. Its an awsome expirience that i havent felt since loong time.
So in conclusion, ANY Decent game at all, WoW,Aion,Muonline,Maplestory,Wonderking, Grind or no Grind, You will look foward to play, if you got a friend by your side.
Good luck
