I don't have one for each console but I have a definite one that comes to mind.

NES: The Guardian Legend - I pretty much never hear this title uttered unless I'm the one talking about it, but it's easily one of my favorite NES games. Part Zelda-like top-down exploration game, part space-ship shooter with awesome weapons to collect and great bosses, this game did hybrid-genre before genre hybridization was fashionable.
