Super Mario Land II for the gameboy color. It is my favorite mario game, yet no one has heard of it (or likes it...)
Also double for Disgea, and add phantom brave and Makai kingdom (but not the other one, it was kinda dumb... I even forget it's name).
And FFtactics, which is a highly underrated final fantasy game (I think only ff6 can compare to it's storyline, and its feel is very unique).
Star wars Galactic battlegrounds (is that what the real-time starwars game by the makers of ages of empires is called?)
