3do - i liked Total Eclipse and Dragon's Lair. TE was the only game that kinda lived up to what I was expecting from the system.
jaguar - ugh.. i'll never get rid of mine, but graphically it was just so bad. Especially the framerates.
32x - i didn't even buy it.
saturn - because the psx did 3d better
sega cd - because Sewer Shark, that's why.
Game Boy Advance.. just because the screen was so dark, and those pathetic clip-on lights didn't help. After installing Afterburner though, I loved it.
Sorry, but Wii. Nintendo is selling to moms.
