Batman, 1989, NES, Sunsoft
A game with some thoroughly excellent (by NES standards) graphics and music, ROTJ also has one of my favourite Batman sprites. Clad in an unusual electric blue colour pallette, Batman looks like he means business, even if he does appear to be wearing some rather feminine thigh-length boots. Not shown here: his very nicely animated cape.
Now we're talking. You could always rely on Konami for good sprites, and this Batman is definitely the pick of the bunch. It sounds like a simple thing, but it's best feature is the fact that all his proportions are right and, even on the tiny scale of SNES sprites, they've managed to make him look as though he's grimacing in a very Batman way. Even the shading of the cape is done very simply, yet it give the cape a satisfying solidness. All in all, top marks to Konami.
