Eh, play PL. I've tried so many MMO's in the app store but they really all do suck. PL has been by far the best.

Order and Chaos if fun - the leveling is anyway. Endgame for O&C sucks unless you have a boat-load of money to spend. Otherwise it takes ages (literally months, even over a year) to obtain the best gear. I do enjoy the dungeons and such, but all I want out of MMO's is to PvP, and PvP is impossible there unless you have the best gear.

Infinity Blade is enjoyable. I did 1 and 2, just not 3 (not enough space on phone). Debating if I should delete Order and Chaos for a bit to try infinity blade 3.
