This weekend I rented "Def Jam: Icon" for my 360 and came to the realization that EA seems to have trouble developing fighting games.
The main issue is speed. First, the fighters move at an incredibly slow pace. Moving them around is like a chore. Second they perform kicks and punches very slowly as well, making it, IMHO, an unrealistic fighter. It was so bad that at times it put me to sleep and didn't bother with it afterwards.
The reason I mention this is because this problem was present in another fighting game done by EA, although a different type of fighting game, Fight Night Round 3. The characters also moved slowly and their punches lacked speed and strength.
It just seems that EA can't make compelling and fun fighters. Now I may be wrong since I only played two of their games, but as a fighting game fan I find it weird how these fighters are surprisingly slow in execution.
In real life fighters throw punches and kicks as fast as possible. There is no delay when executing the move. Fighters also move at a reasonable pace. This element has been present in nearly all fighting games, including boxing games. Hell, even Wii Boxing got things right as the characters move and throw punches fast, making for some exciting matches.
So to EA next time to make a fighting game keep in mind speed. Fighters don't move around slowly nor throw slow punches and kicks. That's not how fighting matches are, whether it be street fighting or boxing.
