I've always been a PC gamer; in the past, the depth and complexity has far outweighed the console games. That is, up until now. I still think technology is in favor of PCs, but by a very slim margin.
I tend to migrate towards RPGs, RTS, and FPS. FPS and console is a great mix, and can be done easily. RPG and RTS, ahh, not so much. This is an area where PCs will probably always dominate.
