I used to sometimes play retro games on my plasma TV, but I try to avoid this whenever possible. I just don't like playing retro games on a 16:9 TV. Either you have to stretch it out, or you have the black bars on the sides. Either way, you're compromising the original vision of the creator by playing it like that. 4:3 CRT or bust.
