Honestly though, all three parties are catered too with Facebreaker. Ostensibly, it is just a button mash-fest and can all the unlockable stuff can be had within a good few hours of play. As Bit-Tech mentioned before too, there's a surprising amount of depth to the combat if you want to study it and the average battle goes on long enough for that strategy to be important.
In the end though, though Facebreaker definitely suffers from some flaws with the AI. The game isn't especially long in the tooth either and is very much intended for group matches on a late Saturday night – an appeal which is ruined by the long matches and fatiguing gameplay.
