Resident Good & Dino Crystians... not to speak of Dante's Paradiso

But the real point is...does anybody know if Aaron's sister's cute?

It's written nowhere that if you don't spend several millions of dollars to develop a game, it will suck.
Don't forget titles like World of Goo.

That's quite obvious indeed: casual games were originally addressed to non-gamers. They didn't buy core games (perhaps they haven't owned any console before, too), and maybe they'll continue to do so.
Casual gaming has only given life to a new market and attracted new costumers.

wait wait wait we're not talking about not-well-developed and bad-quality-games based technologies. That was pure rubbish, it was worse than the visualboy (if possible). Nobody remembers an high quality title made to work with Eyetoy.
