well gta3 was released in october and xbox came out in november. Generally the first month sees a very large portion of the sales, so....
Between gta 1,2,and 3 sony was there. xbox was not. I'm just asking what kind of numbers are we talking about, you say "billions", but i don't think so, that's all.
I think Rock* might have done it free of charge or at least for less than what they would have lost. Rock* explosion happened on the Playstation brand. I would think they would be a little indebted to them. Especially when Sony is known for assisting in the development of games with specialty devs and such.
PS: You are not debating. You are arguing. Anyone who cannot give ps1 its proper due cannot be taken as a serious debater. I don't like Wii, but I give it a lot of credit, it is a great console.
PPS: gta3 was on pc by may 2002.
