TGS08, third-party developers on WiiWare haven't been raking in the cash. Supposedly, they've only sold "hundreds" of copies of their digital wares, meaning it's largely been a bust for them. We're not sure how valid this is, hence the rumor label.
When you think about it, how could stellar titles like LostWinds, World of Goo and Mega Man 9 sell only a few hundred copies? Perhaps the shovelware that is Protöthea and SPOGS Racing only sold a few hundred, if that, but we're thinking that the good games have done pretty well. Hey Nintendo, how about some sales data?
Of course, this could all be moot. It's not like there's much of a source on this one (we've checked the latest 1UP show and the latest podcasts, but we haven't been able to find it there), so feel free to apply salt where needed.
