You know how they get money from ps3 games being sold but what about the ps2 does it happen with it too?

Of course, if they didn't, they would have stopped supporting it a long time ago.

No publisher makes money off games being sold.

They ship copies of the game to retailers, for $X each (varies with the game). This gives them money. Once the copies are out of their warehouse, they no longer earn any money from them.

So if they ship 2 million and the stores sell 100k, they'll get money from 2 million copies.

If they ship 2 million and the stores sell 2 million, they'll get money from 2 million copies (and then the next shipment, but that's not the point).

So no, Sony makes no money on PS2 games which you buy from a store, but if enough are bought, there will be a new shipment, and THAT makes them money.

Oh so its more of the games popularity sort of...well i guess Infinaty ward gots it all down....damn...    

according to this, there are no more licensing fees for PS2 games - http://arstechnica.com/gaming/news/2008/10/sony-removes-content-approval-ps2-now-open-platform.ars

However, I don't know if that is for PAL consoles only, as it was announced by Sony Europe (another link - http://kotaku.com/5070265/the-ps2-is-now-officially-an-open-platform )

I'm sure they do, otherwise they wouldn't be selling them.
