I voted for 5. The Wii was not one of them... Can you guess the 5 I voted for?
I'll take a stab at it:
NES
SNES
N64
GBA
DS
Did I get it right?
BTW, I voted for 4:
DS (What can I say? It's awesome)
Wii (IMO, the Wii will be a new begining for Nintendo)
SNES (Nintendo's golden age in the console war)
N64 (that system had a lot of magic, even though the majority of it's good titles were made/published by Nintendo)
