Honestly, if it's first party, I see it being Ratchet and Clank rather than Jak. Jak's been idle for several years now - Ratchet's still pretty popular.
Not quite right, while R&C's been way more active Jak had a new game about a year and a half ago for PS2/PSP, and had an appearance in that Heroes on the Move game (even if it was by most accounts cruddy). R&C does have the edge however in that there's a new game out this fall, much like God of War Collection was released as leadup to 3.
And while MGS2 had better gameplay I WAS heavily let down by the fact what seemed like one half of the game up and vanished part way through. Made the game feel a lot smaller as a result, but 3 made up for that. I consider 3 and Peace Walker the two best entries anyway, though 1's the one I'm fondest of.
