It sounds to me that it’s really targeted for music production and like, where you have a whole bunch of interfaces to connect like pads, keyboards, mixers, etc. In that case you don’t really need a lot of PCIe slots. We don’t really use PCIe for audio interfaces anymore since USB has gotten so fast.
Honestly from the reviews I’ve seen I don’t think I’d ever expect end game. More “you win… here’s the credits” and now I realize it’s been a long time since I’ve played a game that did that.
