When I was first getting started, I briefly tried Lutris - but was put off by two things. The first was that it felt very complicated. I was new to Linux at the time, and I'm being asked helps of config questions about how to install which-and-what components in order to use such-and-such runners or launcher or whatever... basically just a heap of stuff that I didn't really understand. And when I tried using a recommend 'gold rated' auto-setup to install something, it just froze. So that was disappointing. I decided that maybe I'd try something else.
I've seen Lutris recommended in a lot of places; so apparently it's pretty good. But at the time I used it, it wasn't really what I was looking for. I think a lot of people praise Lutris for the way it lets you have case-by-case special configurations for all sorts of things, which might allow you get some stubborn stuff working. But for me, it felt like more things I could break. I've got enough games that I'm happy enough to just say that if it doesn't work then I won't play it. So I guess Lutris wasn't for me. [edit - Bottles also had a lot of config choices to get started; but I was lucky enough that what I picked worked first time; and I haven't looked at the config since.]
Thanks for the info. That sounds like a decent system. The idea of unpacking into a place of my choosing, and running without an additional launcher kind of appeals to me from a software-simplicity point of view - even if installing the game is slightly more hands on. But I don't think I'll do it that way myself, mostly because I don't really want to further entrench Steam. Valve does a lot of good stuff ... but their dominance in this space still makes me uncomfortable. (And the fact that they don't let you disable the "what's new" advertising bar on the library page is a big red flag for me.)
