Look for everyone on this subject. First they are both great games but Fight Night 4 is just with the analog sticks no button and i believe would get pretty repeditive just dodgeing and punching. On the other hand UFC is the shit with a few bugs………… like quitters, glitches and so on and so on… The good thing is there patching these problems to level up to 200 from 100, quttiers will be punished and super stat glitch to be fixed.
Now I only own one of these games so my opinion is for UFC I play the demo for fight night great game but boring after a while… Ufcd great online and I love to knock people out!!!! So when making a decision on which to buy if you love boxing get FN4 but if you want fun get UFC
