Anyway, what are your top five (or so) favorite games on the MD? Comments would be appreciated, but lists are nice for those with short attention spans.

Here's mine in no particularly particular order:
Sonic 3 & Knuckles:
Duh. Pinaccle of 2D action gaming design. But anyone here should already know that.
Granada:
The only Wolfteam game that hasn't aged violently and developed alzheimer's. Top-down free-roaming shooting action. Excellent, excellent game.
Thunder Force II:
It may not be much to look at, but damned if it isn't great to play. Maybe I'm just weird, but I actually like the top-view stages more than the standard side-view ones.
Dragon's Fury:
BEST PINBALL EVER
ToeJam & Earl:
BEST CO-OP EVER
