Why no games on demand on PS3?

[invetedlotus123]

They already sell some games like GT5P and Burnout Paradise.

I pay loads of money for my games, i paid 180 BRL for Uncharted 2, what is near 90$. But the thing is look at different stores, at the mall a game can cost 300BRL, and at street stores the same game can cost 200 BRl, and at our version of ebay for 170 BRL for releases.

I get most of my games at street stores, i just buy from internet rare games and when i find awesome deals.
