Road Rash CD? Yeah, what it needed to do is actually use the Sega CD's scaling hardware. It's absurd that it didn't, the Genesis Road Rash engine never was that great (the scaling's only mediocre, and the framerates terrible!), when they finally had a chance for something better they should have taken it! But not only is it running on the old engine again, but for no apparent reason the 2 player mode is gone? What happened there? I mean, I like that the music's from the 3DO game -- and you actually can hear the rock music ingame, unlike the 3DO version and its ports -- and it's cool that the videos, menus, and interface are as much like the 3DO game as they could get on the Sega CD, but when you get to the actual gameplay, it completely falls apart, pretty much. The same bad framerate of the Geneiss games, no splitscreen multiplayer unlike Road Rash 2 or 3 on the Genesis, absolutely no graphical enhancements...
And it's a 1995 game, too. It's not exactly from early in the system's life. And it's not a port of a Genesis game, it's new. There isn't a good excuse for how little effort they put into the most important part, the actual gameplay.
