They're not making more they're just selling more.

Read the attached article, it's their response to their sale: http://2dboy.com/2009/10/19/birthday-sale-results/
But relative to other models the "pay what you want" is a terrible failure - any of those games could have singlehandedly grossed $30,000 to $60,000 from the number of sales they've had today, and that's going to lose a big chunk to advertising but still make them a lot more than $1.66 a sale.
Appstore-like pricing is the exception, not the rule.
That some of the 6000 purchasers today would not pay $20 is irrelevant, others would and others from the remaining millions of game players would too.
You also disregard that I already factored in a 50% - 75% discount - the prices I put assumed a $5 - $10 price on sale.
Cheers.
