For Rocket league you need to manually enable proton under properties.

Its running without problems for me now

AFAIK steam has optional drm. If the devs dont use it you can play the games without steam. I think it says on the store page if it’s drm-free

Nothing is gonna change. Consumers gonna consume

People will preorder the next cash grab and whoever cares about quality games will just have to wait. Although i have to admit that it will be pretty much impossible to match the love and care larian poures into their games.
