Once upon a time in the distant past when I owned and original XBox I also played the very first Halo... Damn good game, I just never really got into FPS on consoles, then COD:MW came along
I thought the same when I didn't own a console/try a FPS game. I thought how the hell you can play a shooter with a joystick, when, say, on the PC everything can turn against you in miliseconds, if you don't move your mouse fast enough. But as it turned out, fps console gaming is a lot of fun when you get used to the controls.
