My favorite Megadrive games (besides the uncontroversial 3 Sonics which I have already played to death) were: a version of Micromachines, Psyco Pinball and (yes) Sonic 3D. I'd like to have them all back on the Wii, but I'm not very confident.
PS: 2D gaming was just great. To this day, that Pinball game as surpassed any 3D Pinball game I tried. Same thing for that version of Micromachines. Hell, I never could get into the 3D GTAs after I fell in love with the first one...
