I can think of exactly one Sony studio that is only ever working on one series.

ND completed 3 uncharted games before moving on to tlou.

Don't like the new name. Black Tusk was better.

Sucker Punch did the Sly series on the PS2 though, Guerrila, while they have only worked on KZ til now, are working on a new IP, Sony Santa Monica, while their only fully internally developed IP is God of War, they are basically the colab studio of Sony, as they have co-developed so many projects it's insane. Polyphony though, has indeed only worked on GT.

Guerrilla have only ever made Killzone for them (new IP coming, like LH), Sucker Punch have done Infamous since the PS3 was born, Polyphony = GT, Sony Santa Monica cancelled their new IP, working on a new God of War (which is their 5th)

I don't like this. Reason: They didn't make Gears of War. They assumed the name of something that they didn't create. I definitely don't approve.

Guerrilla is working on a new IP. Sucker Punch got to change IPs once, who says they can't do it again? Polyphony, yes. Santa Monica are a working on tons of smaller projects next to GoW and, like you said got a chance, 4 years and who knows how many millions to make a new IP and failed.

And yes Lionhead is big MS studio that gets to try something new instead of always doing that one IP, that's good. Since I personally feel that there's nothing more creatively draining than always working on the same shit, one of the reasons so many people go the indie route nowadays.

I'm not talking about ND.

and who says the ms stuidos can eventually put out diff games

so basically they have been 1 game studios as most sony stuidos are. 15-20 years and maybe 2 ip is essentially a 1 game studio.
