I am hardly spoiled. While I admit I have a Wii, Gamecube, Laptop, PS2, DS, and a TV (just a simple $90 20" CRT), I bought all of this with money earned from working P/T at a nearby greenhouse. I also have around $3000 dollars raised towards a car, and I still have just over a year to go until I am 16. I'll turn 15 on the 30th (happy birthday to me).
Nothing wrong with the gamecube. My LoZ:TP is on the GCN. I didn't get a Wii until almost three months after getting the game.
BTW: I agree with all your points to improve the next game except the 'smaller temples' clause.
