I recommend the same. For OP’s use case, it’s the best bang for your buck by far.

If you don’t use suspend mid game, what do you do? Do you shut the device down in between gaming sessions? Or do you just save and exit the game and suspend the OS level?

I don’t understand how that’s a problem. Can you go into a little bit more detail about what you think the consequences might be to manufacturers choosing to use Steam OS or some other Linux operating system on their handheld devices?

It wasn’t last night. I did read that it’s usually within a week of the iso download, FWIW.

How soon is it expected to be released via upgrade channels?

It doesn’t. I’m not really interested in multi-player games of any kind. Partly because I don’t have the time to git gud, and partly because my gaming interest is primarily getting lost in a narrative world.
