Playstation usually promotes a very specific type of indies, basically indie games that feel like AA games with cinematic storytelling. Things like Stray, Kena, Shifu and Tchia are what they prefer to promote while strategy games, RTS, simulators and builders are barely acknowledged.

The thing with indies is that you really need the golf story, into the breach and wargroove type of games to create variety. This lifts up the AA like indies too because they look different from the other indies.
