I just don't see the appeal of buying EA. Like you said, they make their money on sports titles for the most part and the leagues can force those to be multi-platform. Dice and BioWare are probably the big draws from a studio standpoint, but I question what talent is left. EA has a massive catalog of IP but you need to create studios to resurrect them. I'd rather just approach EA and try to buy or license the IP you are interested in making a game for.
Keep in mind, I thought about that like just buy the IP, but you still need the teams and I believe they have great value (use that joke as may lol) with those teams and IP together.
Criterion
Code Masters
DICE
DICE LA aka what ever the fuck the want to be called right now
ReSpawn
Bioware
and many more.
I think it can work, they have a stable of great IP and those teams can be restructured, fixed, more added to them and creative freedom given to them so they can freely create, with their tools how they feel like it.
vs
Rushed, forced engine, forced MTX etc.
I feel greatly that it can work and even those teams bought can work on IP Sony has that they themselves have neglected.
Code Masters Motorstorm
Criterion Driveclub (maybe not lol)
DICE MAG 2 (horrible name btw)
ReSpawn Socom
I feel it can work, they have list of great IP, I feel most of those teams are very talented under a horrid publisher that seems to promise more then deliver and lots of issues we've seen seem to be more so based on how those projects are treated by the publisher then the team alone. The release date and working on a engine they don't normally use on top of all the MTX stuff, I want to see how all that shit plays out under a different publisher.
If anything, look at how great Star War Fallen Order was and how it was received. No MTX, no forced MP, no forced engine, they got to use Unreal like they wanted and not forced to use Frostbite, now imagine that concept applied to all EA studios? Under Sony, it could be a thing of beauty lol. So I only see them doing the whole buy out vs just IP as thats a lot of work and Sony already doesn't have the teams for some of those IP.
