It's better because of the storyline, but there are a lot of downsides. The fighting style seems very in and out, with no horizonal moment really. I find going someone with bigger reach and just hammering away with the jab to be the best strategy as the in and out movements make it easier. Saying that, after a patch (and I havent played it much since), jabbing takes a ridiculous amount of stamina away. I go Lennox Lewis, throw my jab (a lot to the body aswell), and somehow I'm completley drained at the later stages of the fight. My opponent is throwing all power shots, and I'm landing to his body a lot, and I'm the one that's tired? I remember looking at the stats after losing online. My opponent threw more, like 90% were power punches, and I still drained first.
I'm probably the best at keeping threads on topic of all time.
