I don't know, I had fun with the SNES but never as much as I had with my Genesis. I owned an SNES for a few short months and gave it to my brother... bought it cheap with a few games from a friend so I didn't feel the need to charge my bro anthing.
For Genesis, my first game was an awesome starter game for the system... the first X-Men game. Hell, at the time I didn't even have a color tv and played the hell outta that game.
I always ask Genesis fans, which games do you identify with? I always have trouble picking out good Genesis games.
the abovementioned X-MenNBA Jams
-- I first played it in Vegas, spending hours in the arcade in the casino tearing that game up... and when it hit home consoles, I had to get it. I was blown away at how much the home version was like the arcade version, back then a rarity. Flashback
-- advertised as the first cd quality game on a cartridge. It was freaky and interesting and I got sucked in.
And another thing the Genesis had over the competition? The NOMAD, which, IMO, wins for best handheld console. It swapped it's games out with Genesis so no need to buy seperate games, you could hook it up to a tv and use it as a Genesis... hell, it even had a prot for a second controller to plug in. I actually still have mine.
I agree PS2 is at the top. NES, as well.
