Best first party PS game ever, and why

[Vodacixi]

Jak 3. This game was like a very good all you can eat buffet gameplay wise. It did everything, and it did it all great. It was a 3D platformer, an open world sandbox experience, it had third person shooter mechanics, vehicle sections, magical powers, a good story for what it was, great soundtrack, good graphics, lots of side missions and optional challenges that unlocked very cool stuff...

It was THE game for me. And it still is.
