Even though there are some minor annoyances I have with this game, I found this title to be very satisfying.
There are a great number of control options (I chose swing mode 2). A tutorial is provided for each option for your convenience.
The story mode is pretty fun. My wife and I had fun breaking a sweat trying to serve beatdowns. Heck, my wife even won a match (by decision, of course). I think that's the main thing, fun. You can try to fight in a technical manner like a boxing sim, but I found it much more fun trying duck the opponents punches to get in close and unloading a barrage of combinations.
My main gripe is in the storytelling. Most of the blame could be placed on the voice acting. I would have preferred to hear the original japanese voices with subtitles (any good game originating from japan should have this option especially if it was based on a comicbook). Anyhow, I'll probably end up buying this title after this rental based on the amount of enjoyment I received. Just make sure you go through the tutorial with each of the different control options and learn the special moves.
The sequel might be better! I had hopes for this one and in return I wasted a Q slot. The controls are horrible (you cant move the character) when usining it like Wii Sports. The camera has issues, and the graphics are ok at best and the story is short. I returned it the same day I got it! Wait for EA to bring Fight Night Round 3 (or 4).
