Astroglide,
You kick ass. I'm really glad you posted that first link.
Housenuts said
up here that you'd use four controllers for some N64 games. But I just looked into it and the only (current) N64 games you need four controllers for are Star Fox and Mario Kart 64, so I can skip it.
Here's where you can see which games are currently downloadable on the Wii.
How much extra memory is needed? Have you guys run out of space?
Also, I just noticed that
Walmart is offering a package deal with the Wii, a second controller, a second chuk, Wii Sports, Donkey Kong: Barrel Blast, component cables and a choice of four additional games (one of which would prolly be Wii Play) for $580. Options are available. Maybe this'd be my best value.
EDIT: I just priced it out and that isn't a great value.
