you forgot Sony London had to be shut down because their live service game sucked. Maybe they'd have released a banger already if they were working on a 1p game.
Sony London never released a critically acclaimed game.
I would say that Naughty Dog significantly surpassed Insomniac after the PS2 generation with Uncharted having significantly more success than Resistance.
Sucker Punch would have rated below Insomniac.
Right now I think the Sony rankings are as follows:
Naughty Dog - 4 successful franchises, all original IP, technically most advanced studio, 2 franchises that can sell games with more than 10 million units
Bungie - Largest studio, 2 successful franchises, all original IP, currently owns 1 IP, working on bringing back Marathon
Santa Monica - Only 1 IP, but sony's current top original IP
Polyphony Digital - Only 1 IP, but the longest-tenured successful IP
Guerrilla Games - 2 successful franchises, all original IP
Sucker Punch - 1 very successful franchise, all original IP
Insomniac - Very successful with licensed IP, but 4 well done franchises, biggest overall franchise for Sony at the moment, expanding to Wolverine/X-Men
Nixxes - Extremely consistent technically
Bluepoint - Extremely consistent technically
Asobi - Not really a track record for success, though critical acclaim
Bend - Mixed, but Day's Gone and Syphon Filter were moderately successful for their times, they haven't had much critical success lately
Housemarque - Returnal sold okay
Media Molecule - Critically acclaimed, but lack of financial success in a very long time
San Diego Studio - financial success, but only works on one IP, which seems in pretty serious decline
Firewalk - Pretty mixed impressions so far, but could boost up if the beta is successful for Concord
Firesprite - Very mixed
Haven - Nothing worth talking about so far
I don't think it's a coincidence that the studios sony just purchased are in the lower half of this list, not only do they have less track record or perhaps no track record.
Overall I ranked studios based on technical prowess, original IP, generating multiple franchises, critical acclaim, and financial success, and overall value.
