Bleh. You people and your Ocarina of Time
There just can't be ONE favorite Nintendo game...
NES: The Guardian Legend, Star Tropics, Captain Skyhawk, Duckhunt (BLAST YOU CACKLING DOG. BLAST YOU.), Contra
SNES: Secret of Mana (GREATEST GAME OF ALL TIME. Too bad it's sequels aren't like it... D: ), Super Mario World
I think I'ma stop this list now. It'd take a year and a half to write it.
And to those who adore the Zelda games...
You can't really say anything if you haven't played a Zelda game before Minish Cap.
GO BUY A GAMEBOY.
GO BUY THE ZELDAS.
