As for myself, I'm kind of enjoying Armored Core VI. I'm an AC noob so I have no reference point, but it's a neat game. Delightfully simple in a way, although I haven't gotten far yet.
The biggest thing to get used to is the movement. One would imagine a certain level of slowness when giant fucking robots move, but no, they zoom and zap all over the fucking place. At first I hated it, now I'm starting to accept it. It does add an element of skillful evasion and smart quick pathfinding into the game.
