I know these are old and many are likely familiar with them, but I myself have only just come across the wonders of The Angry Video Game Nerd. :o His reviews of TMNT and Karate Kid are spot-on, by the way.
Anyway, I found these two reviews to be hilarious:
Sega CDSega 32XBack in the day, I never had a Genesis. Stuck exclusively to Nintendo. Would have LIKED a Genesis (mostly at the time because of Shinobi III), but I was a young squirt, and it basically all depended on whether or not my older brother wanted one, because my mom would have bought another new system for TWO of us, but not just one. Sadly, my brother never has cared for the Genesis and still sort of slams it (even though, through the wonders of emulation, I've discovered what a great system it is).
But anyhoo, I still hold the opinion that the SNES is far superior to the Genesis, in every way, including games catalog. And these reviews remind me of two cousins of mine who were big into Sega and mostly slammed Nintendo. I remember when the Sega CD came out, I thought it looked like a pile of crap. I sort of liked the idea of CD console games, and Sonic CD looked really cool (I never got to play it until a few years later on PC, and yes, it does rock--second best Sonic game, right after the first one, I'd say), but most of the games just looked like garbage. Still, my cousins defended it, and made fun of Nintendo for not releasing a CD add-on (like they had planned with Sony, I believe--the original PlayStation).
Now I remember the Sega CD looking like poo, but I didn't remember it being THIS bad. Those games are atrocious! I would love to play Snatcher, though. I've wanted to for like 7 years now.
Now as for the 32X, I always just assumed it was crap. And looking at that video, yup, I'd definitely say so. Even Knuckles' Chaotix is bad (which I emulated, yay).
