Resistence was good, and the only fps except timesplitter that i enjoyed on a playstation console. I was never either a fan of the damn slow dual shock 2, but with sixaxis and recistence my experience has indeed change.
Demo wasnt so good and fun like the whola game. So i recommend you, if you are sceptical after playing the demo, to buy the full-version. The Game is truly growing and keep getting better after some hours.
But compare to Halo 3, as a FPS on a console? - No, its two steps under. The Master league.
So no suprise its ''the winner''.
Resistence vs Call of Duty 3 should be equal, and a interesting fight. So no suprise winner at all.
