What's really amazing is how strong the list of games is. There's only a few minor changes I can think of that would really make it the definitive list.
(ones I'd wish for)
Balloon Fight
Castlevania
Donkey Kong
Double Dragon II: The Revenge
Dr. Mario
Excitebike
Galaga
Ghosts'N Goblins
Gradius Life Force
Ice Climber Ice Hockey
Kirby's Adventure
Mario Bros.
Mega Man 2
Metroid
Ninja Gaiden
Pac-Man
Super C Contra
Super Mario Bros. 2
Super Mario Bros. 3

Bubble Bobble Kung Fu
Castlevania II: Simon's Quest Castlevania III
Donkey Kong Jr. Gun.Smoke
Final Fantasy
Kid Icarus
Punch-Out!! Featuring Mr. Dream
StarTropics
Tecmo Bowl
Gradius Life Force I agree with this change.
Ice Climber Ice Hockey Sacrilege man! Ice Climber is a classic!
Super C Contra I agree with this change. I have to wonder why they didn't/couldn't/wouldn't use Contra
Bubble Bobble Kung Fu I'd keep Bubble Bobble over Kung Fu personally.
Castlevania II: Simon's Quest Castlevania III CVIII used custom sound chips so that's probably a good reason why it wasn't chosen.
Donkey Kong Jr. Gun.Smoke I like Gun.Smoke (prefer the arcade version) but not at the expense of giving up DK Jr.
Here's the ones I'd prefer...
