It was telling being at the first Steam Dev Days and hearing again and again how Valve distinctly, publicly, never wanted any exclusivity on anything coming to steam, they'd never ask for it and it wasn't something they were interested in. Same on VR, they never wanted to 'own' it or it's ecosystem, they just wanted to see the medium grow. Valve doesn't do everything perfect, no one does, but these points earned a tremendous amount of respect from me.
And it will be probably remain a good company while Gabe us around. But no one lasts forever. And that could be troublesome in the future. Don't get me wrong. I love steam. Have a steam deck. Buy about half of my games on their (a few on gog and rest on console). But it could be a problem in the future.
