Most of the ipad games are mini game for killing time. Such as the famous apps angry bird, fruit ninja and i-fart. However, there is a quite good MMO game for ipad. The game run very smooth on ipad and we play with real human while joining the same server. Some people even say that is a kind of ipad version of word of warcraft. Well, I think this cannot compare with WOW. Yet it is still nice.
