Playstation games for rent?

May be...

I'm getting my first PS3, I notice that at video rental stores they have games for rent.Does this mean you rent the game and have it for one day and then that's it? Does the PS3 come with any games at all?

The PS3 does not unless you buy it in a bundle. Usually games for rent are 1 week.

Dude, game rentals has been going on since forever, even before PS3 (have you heard about Blockbuster Video?) It's not for 1 day... 1 week at least. It's about $9/week. There's also game trade-ins and you can also buy second hand games. PS3 comes with games if you buy a bundled deal.
