Just to consolidate responses to Broodwars and Kairon. Sure, there are a few good games on the wall of shame. A few. But most are the sort of shovelware the likes of which even God has never seen.
Pro's talking about brand mistrust and why your discerning Wii gamer will stick to Nintendo. If he made a "Nintendo Wall of Glory" You'd see most of their games aren't "garbage" even when they are low budget. Nintendo's games aren't "90% crap." Some may not be your cup of tea, but none of them were foisted onto Wii owners like "Space Camp" or another Wii Sports ripoff as late as October 2009.
Also it shows that because the the titles released earlier in the generation from third parties got more sales than their later ones, initially the Wii gamer was trusting of third parties until they started getting real garbage dumped on them. Then they rejected and rebuffed their games outright, even if they were good (Sega felt this) simply because of a ruined first impression. It's cause and effect, a consequence of treating your customer like an idiot, and entirely their own fault. Maybe if they had tried harder in 2006,2007, and 2008 they wouldn't have felt the sting of people's disinterest. But instead, they blame me, you, Nintendo, the economy, etc. Everybody except themselves and their shoddy development, poor marketing, and ruined brandname for the majority of gamers.
And really, who could side with the third parties here? Who looks at this list and says "That's a great effort! That totally matches Nintendo's 40 or so games." Considering both the sales AND gamerankings AND amazon reviews AND professional critics would disagree, anybody who would would be in the vast minority and look like an apologist or a shill.
