[quote name='BigHow']Assuming that Nintendo keeps their word and this is the only way to get the Doc Louis WiiWare game, then you are getting a playable collector's item. Assuming there's some secondary market demand for it, any Wii with the game download will receive an increase in value.
Granted, it's not the same as getting a DS cart or a disc (which is what you're presumably asking for), but I think we're actually looking into the future of gaming. As we progress to a non-physical media market, collector's items will inevitably end up being either one-time physical printings of niche games (akin to the Mega Man 9 press kit, but a functional game) or limited time downloads.
The limited ability to sell or trade downloads may ultimately kill the "collector's" market in the next generation of systems.[/QUOTE]
You could probably argue that since it is actually impossible to get this game any other way, the value of it is probably a lot higher then a disc would be. If it were a disc, some of those discs would end up on ebay right away. How many Wii's with this download game on it are going to show up on ebay right away? Ever? So in that sense, by being a gifted download game it has even higher value.
EDIT: Imagine after, say, 5 years, if someone had a Wii with all 5 exclusive download games on it? That Wii would be worth quite a pretty penny, most likely.
