I agree on the N64, and the problem with it is that everyone is nostalgic for "the system," but in reality they're only nostalgic for Mario 64, Goldeneye, Conker, Mario Kart, Ocarina of Time, Banjo-Kazooie, Smash Bros., and Perfect Dark. It's not that the N64 has a top ten, it's that it basically only had ten good games total. And bangers though they may have been, everything else on it was crap.
I'm sure two or three people will pop out of the woodwork now to argue with me and insist that no, back in the day they really did love WCW Mayhem or 1080 Snowboarding or the butchered piece of shit version of THPS or Chef's Luv Shack or whatever the fuck, but that's the thing: It's always back in the day, when you were a kid and only owned four cartridges, and you didn't know any better because that's all you had. Nobody goes back to play any of the remaining 378 games now.
