I'd vote to kick Space Megaforce. It felt like nothing but an excuse to cram a bunch of Mode 7 effects into one game, not that a few others like CV4 and Axelay weren't. In it's place? Castlevania: Dracula X! I found it quite difficult, with lots of little tricks in the level design. The bosses weren't so hot, but... it was still fun.

Also, I'd replace FF1 with FF3. The SNES version of FF was abysmal.

(the only real FF is Final Fight)
