Genesis - Technocop, Last Battle, Hard Drivin' and Steel Talons. Technocop, in spite of some kickass music, is horrendously boring. The timer runs far too fast and controls are clunky. Last Battle shares many of the same issues with Technocop, though it's actually worse, thanks in large part to the insipid dialogue and piss-poor animation. Hard Drivin' and Steel Talons are just shit. They control well enough, but the framerate moves at half the speed of smell. Awful.
SEGA CD - Wirehead, Double Switch and Cliffhanger. While Wirehead does have a hefty dose of cheesy charm, it's absolutely ridiculous. Having to watch the same shitty scenario unfold over and over again until you figure the correct route is nauseating. Double Switch is annoying to watch on many levels and too complicated to control. Also, I fucking hate Corey Haim. Cliffhanger is also available on Genesis, but SEGA CD takes the cake. That snowboarding section is so damned frustrating, I'd rather play one of the Super Star Wars games on SNES. They seem easier through comparison.
32X - Motocross Championship and B.C. Racers. Motocross is a budget Genesis title in disguise. Seriously, Road Rash II looks, sounds, plays WAY better than this shit-fest. B.C. Racers looks decent, but the music is fucking atrocious and controls aren't much better.
There's some terrible Saturn and Dreamcast titles, yes, but I can't go on anymore. Just thinking about the games I've mentioned depresses the unholy fuck outta' me.
