I've been looking forward to this for some time and based on the demo I'm feeling a little short changed.
With punches being thrown via the right stick, it feels far too easy to throw an incorrect punch. For example, the difference in stick movement between an uppercut and a cross is very small. This constantly left me wide open to a hefty smack in the face, which in a boxing game isn't ideal.
The graphics are good but as mentioned in one of the other reviews they do have something of a cartoon like quality. In some of the close ups, the fighters look like wax works and are certainly not as good as the those in UFC 2009.
The actual physics of the fight seem to work well although punches feel weak when thrown. The haymaker punches feel especially under powered and during one bout I knocked my opponenet down with a punch, which quite frankly my Nan could have taken!?
I sincerely hope that this is one of those games that improves the longer you play it and that the full version will "draw you in" so that the minor flaws can be overlooked.
