Well my goal is not to buy a game until i have saved enough money that doubles the price of the game.

I will probably buy any game made by Enix for PS3.

and probably Team Ico. or maybe even Naughty Dog/Insomnia

I plan to buy all of Naughty Dog's games this gen. Jak and Uncharted are two kick ass series.

My goal is to own 600 games for my PS3. Right now I'm over 30.

Thats an easy goal to set. One of my friends bought every NES game ever commercially released. It is pretty impressive to look at but amazingly expensive to pull off.

I don’t buy any games only based on that, but whenever Bioware releases a game it’s usually a must-buy for me. Has to be on a platform I’m already looking to get games for though.

Yes Bethesda, I own Oblivion(X360), will buy Fallout 3 and Rogue Warrior for my PS3. That is all I think they have announced right now. If they make more I will buy them.

When you narrowing it down to studio, you make it much easier to achieve this goal. A great deal of PS3 owners will buy every single title released by Polyphony Digital or Team Ico. How many games did they make for PS2? 2?

I like all the PS3 titles "confirmed" to be released by Square Enix and Naughty Dog. So probably I will end up with these two company/studio.

I don't think so. I do buy most games made by Atlus, Intelligent Systems, Nintendo EAD (especially Nintendo EAD Software Development Group Tokyo), Retro, and Valve, though.

Wait wait, let's compromise.  They both suck.  Problem solved.
