Well that would at least explain why it's so hard to find actually good games after you've worked through the usual contenders.
I've been feeling for a while now that Nintendo's e-shop has all the issues w.r.t. overpriced, sub-par games steam has, but without all the useful filtering possibilities and community moderation.
OTOH at least that also means that indies have less trouble making it to the console now.
For example, total iphone games are only 10337? Can't be possible, the real number should be at least X10!
