A friend of mine let me borrow his copy. I've only just begun, but so far it's not bad. Graphically it's not going to win any awards, but isn't that true of about 90% of Wii titles? The audio is cool and the environments are, at least thus far, pretty creepy. The controls are odd. It's kind of a like RE4 with the camera and control. 'A' examines things, 'B' swings your weapon, 'C' turns on your third eye vision (think MP visor), 'Z' runs, and 'down' on the dpad enters first person view. There is no strafing, quick turn, or pointer controls. Well, you use the pointer a little bit in the third eye vision mode, but for the most part you don't need the Wii Remote pointed at the screen.
I'll post more as I play.
