This is actually a really good game and is not just a button basher and is much better than fight night.
Firstly the career mode is pretty lengthy and does start to feel slightly the same but if it deos change the difficulty to a higher level.
Alot of ppl say you can just head kick to win but you can't on any other difficulty than beginner because you just get countered and hit with a flash KO (thats why ppl keep losing).
The ground game is very good it actually requires someone who knows how to play the game properly to manage it effectivley and if you can it can lead to a massive advantage over other players who just want to strike. Submissions are not cheating they just mean the other player wore himself down, didn't block transitions and has no idea how to counter them.
The online play can get slightly laggy but only if you have a slow speed internet or bad connection. It does offer hours of fun however (even though there is people using turbo controllers).
Its a pretty much solid game the only thing the online needs to be tweaked to stop cheaters and cut down on the lag a bit but it is really good and i can't seem to get bored of it.
Buy it and play it PROPERLY
