Valve's popular Linux-powered gaming handheld the Steam Deck has hit a new milestone, with 15,000 games now rated either Playable or Verified. And it continues to sell well.
I have never regretted buying one. Took it on a long trip and didn't have to miss out on the games I usually play, plus I play a lot of games I don't normally bother with on my desktop.
It’s my favorite device. I’m amazed at how well it runs pretty much everything I throw at it, including unsupported games like DayZ. I take it with me pretty much everywhere, most recently I was playing Fallout 4 at sea world.
I've really been pleasantly surprised by how well Proton works, and how well the Deck performs considering it's a mobile device. It's actually my primary gaming device now, and I often play with it hooked up to my monitor. Sure, I won't get 4k @ 60fps, but considering my previous gaming setup was a potato model PS4, the Deck has been a step up and it runs way more games than a Playstation. Definitely good enough for my tastes
For me the main limitation is things that require big screen/keyboard/mouse (RTSs and strategy stuff, potentially adventure games like Monkey Island which are awkward on a controller), but i imagine a dock will solve that issue, need to get one at some point
Adventure games are awesome on the Deck with the touchpads. I always configure them so that either one works. That way I can even play one handed while lying on my side.
RTS is much more difficult since you need to be quick. It's enough for the StarCraft campaign but not for multiplayer. I'm currently playing Dungeon Keeper which seems to be slow enough so far.
