Just played the demo off PSN.
I like... but I'm not in love.
I think the PC version that I have is better. If only because I can pop and retract the claws at will. (Hell... you could even do that on the genesis X-men game...)
It's very reminiscent of Hulk: Ultimate Destruction (though Hulk had a much MUCH wider variety of moves that were funny).
I fear wolverine will suffer Hulk's fate though: Not enough competition.
Ultimate Destruction was just SILLY in that... the Hulk, over time, has fought EVERYBODY, yet so far... in all his games, he's fought NOBODY. In the comics he's fought Thor, Spiderman, Doctor Doom, and... oh yes... Wolverine. In the game he's fought the Abomination... over and over again.
In the games occasionally Wolverine has fought Sabretooth... and I think Lavendar Man... but maybe that's in an alternate dimension.
