What is wrong with the genesis Raiden exactly? If it's the graphics, than play it on the system with dithering in affect (illusion of more colors).
I can't even call you guys gamers now, because you are basing a opinion on graphics alone. I keep telling you that the game play is intact and fun as ever.
As for being the worst port, Where do you place the Snes version with its flawed design. Not to mention the Lynx version.
