I am interested in picking up TTA, TM or RftG. I am under the impression these are all incredible games and any of them would be fun, which means I am interested more in which one is a better app to play. - Which has better, more human-like AI? - Which has better multiplayer? - Which has the nicest & easiest to use interface? - Which has a better tutorial? I've never played any of these, so a nice tutorial is welcome. Not the highest priority item on this list, though. Thanks for any input!
