I have multiple..
- Like many others, backwards compatibility
- and while we're at it. Make games upgradable like PS4 to PS5
- System level voice chat. Not depending on the game or smartphone app
- better friend system
- Focus on 1080p 60fps performance, games less than that are simply not allowed. When possible a ingame toggle to quality mode that gives 4K 30fps at minimum.
- cloud save backup on ALL games.
- controller with audio through aux or usb-c
- try less to be different, try more to be better
- actual functioning invite to game option for friends
This is all I can think of right now.
I honestly do not need a different new system. I just want something better than the current Switch in terms of performance.
