I've got nothing but praise for this game. Yeah you can indulge in playing it competitively but even without it the game has so much content that playing it single player can be quite fun. Especially for me, since it's hard for me to find time to play really long RPGs (or any other super-lengthy title)
Yesterday I tried out Battles mode which is basically its rendition of Arcade mode on Medium difficulty and it surprised me how the A.I. was still progressively getting tougher as you went up the ladder. I would have thought they just coded it like "dump random opponents + boss"; but they even bothered to make it a little challenging. They didn't get lazy and it shows.
And they even threw in endings for all characters. So yeah, you can play this totally without caring about frame data or badly balanced characters in multiplayer; you can play it without aspiring to win at EVO or any competitive arena, which applies to a vast majority of gamers out there. I'm glad that NetherRealm actually thought of that gaming audience when they made this, and they realized that not everyone is going to play it like Justin Wong or the minority of players who play these types of games professionally. At the same time, the complexity is there if you want to go deeper with it. There's probably some overpowered characters now but that always gets ironed out eventually.
So yeah, this is probably the most inclusive fighting game that exists right now. Capcom should buy a copy of this game for each guy on their Street Fighter team, play it religiously, and figure out why the fuck they messed up something as potentially glorious as Street Fighter X Tekken, or even the Marvel series. This is how to do it right.
Last thing: I'm glad they didn't re-use too many of the MK animations. There are some good ones in there.
