Xbox360 and Wii
I used to previously own them as well.
Another system I forever shunned is turbografx16 and jaguar. I never played them before and have no intentions to. Maybe if I came across them at the flea/yard sales for $10 buck.
It hurts when some of you say N64. N64 was my most prime main console. I consider it to have developed the hardcore skills I have today. It was also the first 3-D console with one analog joystick. You either were the type that walked into walls endlessly or you were able to get control of the character/game.
