While i'm excited about the Virtual Console, and I will buy games on it, I am going to be very picky about what i'm willing to buy on it. I recently sold my my SNES, and N64, and got around $85 for all of it. I wouldn't be suprised if I only spend about $85 on the Virtual Console in the coming year or two.
You're not gonna find me buying Urban Champion, or Baseball. I'm only buying the triple A titles like Zelda, and Mario 64, which i've recently purchased. So, if people are selective, the Virtual Console is not really gonna cost people like myself much, and they can have perfect ports of some of their favorite Nintendo titles from the past. I also get to play them with ideal controllers, and saved progress, and the sweetness that is the Wii interface.
I honestly think that some people devalue videogames for themselves when they dump 1,000 roms onto their computer or modded Xbox. What are those games really worth to you at that point? You're likely never gonna play most of them, and i've heard their are always some issues with the emulation performance, and of course the controllers are never really set up to play those games perfectly.
I just see the Virtual Console as the perfect oportunity for me to own the select classics I choose to own, and have them all in one place, with perfect emulation, and perfect controls.
