I think it was ND until they decided to go woke and that to have white male protagonists is problematic, toxic, sexist and misogynistic and that their females must be unattractive to heterosexual males, and that their next male characters must be dumb or bad guys. So for me, Uncharted 4 is where ND lost their reign. I didn't like Lost Legacy and TLOU2 for things like that and they aren't my favorite Sony devs anymore.
I prefer Insomniac now. They did a great job with the Spider-Man games and Rift Apart, have a faster development process and now they have Wolverine, my favorite Marvel character. Yes, Insomniac also wanted to include more representation giving protagonism to a black Spider-Man and to a female Ratchet, but they did it with charismatic characters and being respectful to the brands, to the iconic protagonist characters of these brands and to their fanbase.
Dev times are increasing across the board. Santa Monica had one game last gen. Sucker Punch had two as did Guerrilla. Why do you think this is isolated to ND and Druckmann?
AAA games now take 4-6 years of development on average, and PlayStations get released every 7 years. So every team can only release 1 or two games per generation. So they must have more game tracks working on different games at the same time or to share their work with more studios to release their games faster.
For the last gen Santa Monica developed:
-GoW 2018
-GoW Ragnarok
And published/overviewed/supported/incubated:
-Hohokum
-GoW 3 remastered
-The Order 1886
-Everybody's Gone to the Rapture
-Fat Princess Adventures
-Bound
-Here They Lie
-Some PS4 ports of 2nd party games they published for PS3 and Vita
A few years ago they did stop publishing, incubating and supporting 2nd party studios. XDEV will now handle that and Santa Monica will focus on developing their own games. They have been growing and seems they will continue growing so they will be able to work in multiple games at the same time as Insomniac does. We know that in addition of Ragnarok they are working in at least Cory's game and according to Cory they have 'many things in the works', so maybe they are working on more than 2 games at the same time.
I assume Cory may be working on a new IP while also overviewing how they reboot the next GoW, that since seems Ragnarok will close the Norse arc it may go to another mithology. Tsushima got Japan, so I think they will go to Egipt next. And also may be making experiments to see what new things they can do pushing hard the PS5 hardware.
Naughty Dog will have released for this generation:
-Uncharted Nathan Drake Collection (developed by Bluepoint)
-Uncharted 4
-Uncharted Lost Legacy
-TLOU remastered
-TLOU2
-TLOU2 Factions (it was originally TLOU2 MP mode so I think it's fair to assume will be released for PS4)
Guerrilla:
-Killzone Shadowfall
-Horizon
-Horizon 2
* Also supported other games like The Last Guardian or Death Stranding, but not sure until which point
Sucker Punch:
-Infamous Second Son
-Infamous First Light (standalone DLC game)
-Ghost of Tsushima
Insomniac (many of these were small VR or Magic Leap games):
-Ratchet & Clank 2016
-Song of the Deep
-Edge of Nowhere
-The Unspoken
-Spider-Man
-Seedling
-Stormland
-Strangelets
-Spider-Man: Miles Morales
Knowing Spider-Man 2 will have the same director than Spider-Man 1 and that Wolverine will have the same as Miles Morales, and Rift Apart had another one, seems they have at least 3 gamedev tracks working at the same time.
