All AAA devs including and most specifically
Nintendo pretty much only find success with legacy IP, Remakes,Remasters etc.
The rise in digital store fronts and subscriptions, cloud, etc. Has taken the power away from AAA publishers to control what people buy.
In response they have created a $200+m gate, where only huge publishers with lots of money and already popular IP can compete.
This makes pretty much any kind of risk at the AAA level untenable. Games have to be huge and safe or have some type of long term monetization to exist.
The costs keep going up, and game sales pretty much can’t get any higher. As the console market is not growing, so profit margins are shrinking and risk is going through the roof, one game can kill a studio.
All of this has created a bubble that AAA publishers are now scrambling to figure out.
