Well, I had an itch earlier this week to hook up my Genesis. The original RF adapter was busted so I got the AV cable from Amazon.com and hooked it up and whoa it is quite a shock to the eyes to see a 16-bit gaming system on a 1080p TV. After a while you adjust and it's certainly possible to play the games but it's still pretty ugly playing games with 240p resolution (or whatever the hell it is).
Captain Obvious over here, I know.
