Capcom actually spent a near decade going from AAA to AA back to AAA development. That era of AA games nearly bankrupted them. I think the "Less is more" applies to games more than other media. You can try making money by volume (Multiple AA games per year), but people only have so much time they can invest in a game. So you're better off staggering games. I mean, how often do games just die in November because they're competing against other massive IPs? A publisher is better off moving games into off times when it releases nearly by itself. I also think this is partly why Sony's titles tend to do extremely well. They normally release games in the spring/late spring. That's when most publishers tend to not release anything.
When I say AA i really mean an indie level of commitment,.. studios that are only ~30 people. hades came from supergiantgames which according to my internet search has 20,.. but also made a GotY contender.
and sure,.. it's not likely to be the generator of massive profits but it is also not likely to be the generator of massive losses. but for sony (a platform holder) it is important to try and get a variety of games on their platform to attract a variety of consumers. personally the #1 reason i'll probably get a switch next year is sony has basically 0 kid appropriate titles outside of lego which i'm 1 game away from finishing the entire library of games in the last year. i tried playing sackboy's big adventure with him but midway though the second world things were just too hard for him.
puzzle games. 2D platformers. shumps. rouge-likes. rhythm. medriodvania. while not wildly popular they have an audience and if sony has more of them than ms or nintendo you'll draw in that audience to your platform instead of the competitor. and occasionally you'll get a break out hit like hades or journey. but the point isn't entirely profit,.. it's bring diversity and consistency of releases to the platform in an industry that is collapsing into just a few high profile releases a year.
