Solasta: Crown of the Magister has incredible Steam Deck support btw and is currently on a 60% sale. I bought it as I have some flights coming up and wanted to get more familiar with D&D5e before BG3 comes out.
Obviously buying it right now is a bit like "we have Baldur's Gate 3 at home..." but I was pleasantly surprised by how great the Steam Deck support is. It's like they must've tested it on the Steam Deck specifically.
There's a few minor issues with small text, but aside from that it's great.
It's awesome to see games get official controller support for the Steam Deck. Hopefully Baldur's Gate 3 will have as great support as well.
I play Solasta exclusively on the Deck (as it's my only PC now), but almost ALL that time is docked.
The tiny text is a deal-breaker for my 40s eyes, re: playing it handheld. I'm working on a magnification screen rig at the moment (awaiting the parts) to address the issue in general, but just by default, on an 800p 7-inch screen, it's just too small.
I'm hoping that developers work on having clean and scalable fonts and UIs, as a growing percentage of PC gamers are going to be portable.
It can be done right. For example, I bought Inscryption on the last steam sale and played through almost all of it handheld, and every font in that game is either large as a percentage of screen real estate, or it's very, very clean and easy to read when smaller. That was a great experience on the small screen.
If I were you, I'd look into setting one of the back buttons to trigger the screen magnifier. Not a perfect solution, but it might help enough if you want to play on the go.
Appreciate the suggestion, I usually set one of the trackpads as the magnifier and mouse. It's not ideal though, the zoom in is pretty extreme, so you lose parts of the screen.
