My Top Ten Wish List -
01. Insomniac Games / AAA
Proven history, great developer with an excellent track record when working with Sony. When working with others, not so much. Spider Man 2 and Ratchet & Clank 2 are going to be PlayStation 5 exclusives anyway which will surpass their original games respectively.
02. Remedy / AAA
Perfect fit in my opinion as all they develop is third person single player story and narrative driven games. Great overall developer.
03. Ready At Dawn / AAA
Visually, one of the very best developers. The talent is clearly there. Just need to put the focus on other elements besides visuals and they would be awesome. Have a history of working with Sony.
04. Supermassive Games / AA
Would be a cheaper and not (but not great) replacement for Quantic Dream. Was originally developing Until Dawn for PlayStation 3 until it got moved to PS4 instead so Sony obviously saw something in the studio to do that as opposed to cancelling the game. Their games are solid and would probably be one of the cheaper acquisitions.
05. Housemarque / AA
Have worked for the most part exclusively with Sony and have developed some amazing twin stick arcade shooters and plat-formers. Perfect fit for $20 PSN digital only games and as free games on PS Plus. Those who are fans like me would buy their games day one. Besides, I want my freaking DinoNation damn it!!!
06. Arrowhead Studios / AA
Developed a game called Magicka for PC in 2011 and a bunch of extra content. Developed Helldivers which is an impressive 82 overall on open critic as a solo or up to four player co-op isometric twin stick shooter. Like Housemarque, would be a perfect fit for $20 PSN digital only games and as free games on PS Plus. Would also be a cheap acquisition.
07. Bluepoint Games / AA
Exclusively a remaster/remake studio, they woudl be perfect to handle the upgraded ports of PS4 games that become backwards compatible on PS5 while also remaking older games to see if they hit. Would also be a cheap acquisition.
08. Kojima Productions / AAA
Not much to say here. Only reason this developer is this low is because I don't believe that he would leave working with Sony. It's simply a prefect fit. With that said, it wouldn't hurt if he officially became part of Sony's first party studios.
09. Yang Bing / AAA
Yang Bing is the lone developer behind Lost Soul Aside demo years ago that was so impressive that Sony signed him, gave him a studio and a team. Fills the SoulsBorne genre, adds a Chinese development studio and keeps a young talented guy in house. Probably wouldn't be expensive either.
10. Crytek / AAA
This studio is only listed because of the CryEngine which is still used and could be licensed out by Sony to development studios that want to use it as well as acquiring their franchises such as Crysis. Would be a good alternative to develop a new Killzone game, Resistance game or Crysis 4 while at the same time, allowing Guerrilla/Insomniac to develop sequels to their previous PS4 titles and new IP's. Also adds the First Person Shooter genre back to Sony's catalog.
Those are my top ten development studios that are on my wish list. Covers AAA/AA games, fills a bunch of different genres, can license out CryEngine and their tech to other developers and added a veteran like Kojima and a young talented guy like Yang Bing all at the same time. Plus, the majority of the list would probably be pretty cheap actually. Insomniac, Remedy and Kojima would probably be the most expensive.
We'll just have to wait and see what studios Sony acquires.
