Valve have my trust just by being privately held company that can actually plan for decades ahead instead of try to appease major shareholders or black rock.

It took them 10 years to make Linux a competetive gaming platform.

They invested in VR early and still do a lot for this niche market.

They brought back hanfheld PC from being niche chinese devices to being mainstrean and maintain support for Steam Deck for 5 years.

As game developer I do find 30% cut abysmal, but it's not any worse than consoles and I dont like Epic as a gamer for being awfully anti-consumer. I certainly dont want PC game market to be controlled by chinese Tencent subsidiaries.

Getting involved with epic games as a game developer feels like willingly feeding yourself into the mouth of an open shark. Yeah maybe they have a better cut, but I'm still not doing it

Valve rightly get a lot of flak for the gambling and high % cut, but you do get a functional useful service in return at least, that doesn't appear to be actively trying to screw you over
