The new physics engine for EA's Fight Night Round 4 brings you closer than ever to the true experience of having your head sliding against a large sweaty man's armpit.

It's all well and good when demonstrating boxing with a bald guy. What I was to see is real-time hair deformation as it slides underneath your opponent's underarm, perhaps with a little hair-hooking, just in case the other boxer didn't shave recently. Only then will I be truly impressed. Until then, I'm only slightly impressed.
