That’s an embarrassingly small number of games for a PC… a PC should have access to far more games than that.
I’m sure that’s just the “verified” games, but it’s pretty dumb to flaunt it like it’s something impressive.
As a Lenovo Go user that can access both worlds this is an interesting article to see where I stand in terms of overall access to games. But shouldn't a Steamdeck have more titles? As far as I know you can't you also side install Windows for games from other platforms?
I bet the amount of games that are what most would consider fully compatible is much higher than the amount of green checkmark games (valve just doesn't have time to check every single game out there).
What I would consider falling in that category is full Xinput controller support, no keybinding necessary, and Fully functional under proton. Yes you can get other games working but that's the optimal conditions for normies to play the games without fiddling.
