@Kasz216, I asked you a simple question how steam(and/or developers) will not loose money when I am going to buy less games. Also as for the basic economy, services like gamefly need four huge wherehouses, hundreds of employes, deal with damaged dvds and deal with disterbution, Steam on the other gand need to host server farms and pay for bandwidth while in my extreme example all i'll need a simple ~server and hosting plan(i.e. if thier payment plans wont change I'll make millions of leaching of thier hardwork) or if you want in the most basic case, it will cost me a tweet between my friends.
