I played the demo and loved it (not a huge FPS fan), and I even managed to beat it without dieing, which was nice. Not to hard, not to easy, and overall good controls. Awesome graphics, but I don't like how the menus do that focus thing, drives me crazy.
I then went to the RE5 demo for the first time, and I couldn't believe that with so many zombies coming towards me that I had to go to the inventory and combine the gun with the ammo to reload. I got totally owned by the controls, not the zombies. Needless to say, I now have no interest in RE5 cause I died cause I couldn't reload my gun.
