>> A "Nintendo Seal of Quality" would be really great for games.
Every (legally sold) Nintendo game had the seal. That didn't stop developers from flooding the market with really, really bad games like X-Men and Heroes of the Lance.
Granted, this didn't stop publishers from releasing really terrible NES games like Action52 (of Cheetahmen fame), but of course those were not licensed by Nintendo and did not have the seal of quality. Most of those games were QBASIC-level bad.
