I think the problem is the game industry/game journalism industry corruption. Spore was reviewed and got many 9/10s. That's enough to prove something's wrong.
When people stop trusting these liars, and rely only on word of mouth and forum feedback, then we'll see an improvement in the quality of games. As it is now, reviewers suck up to the games companies because otherwise their magazine/website has advertising pulled. So publishers can just boot a game out onto the shelves and they know if it's so hotly anticipated at E:TW was, it'll still bring in good reviews.
Unfortunately it'll be a while before people learn not to be such blind sheep.
