Steam’s been fantastic! Problem for me is that some of the battle.net games aren’t on there. If there’s a way to download those somewhere and run them through Steam that’d be incredible. I didn’t even think to consider searching around for that possibility. I’ve seen people run Diablo 4 on their Decks so it’s clearly possible, I’m just still learning how to troubleshoot Linux and I’m trying to be extra careful since their OS doesn’t have much in the way of guardrails to prevent dummies from nuking themselves
I installed Mint this past spring and fiddled around with it briefly every once in a while but I’m not a tech guy so there was a little bit of a learning curve on stuff like getting a second monitor to work, stuff like that. I’m sure you’ve already found out that there’s TONS of documentation and forums for questions, it’s just a matter of feeling kinda dumb for a little while as you troubleshoot. I switched over to Mint full time a few months ago and haven’t looked back. I’ve still got Win10 on an extra hard drive just in case but I think more and more of reclaiming that space for Steam now, I don’t miss Windows at all
