Yeah. I also use Bottles for GOG / itch games that don't have a native linux version. And I'm pretty happy with how it works. Things install smoothly and easily, and it has a very nice menu for the games I've installed. Here's what it looks like:

However, there have been some hiccups along the way that might have caused less patient people to give up. In particular, it took me awhile to work out that although I could tell bottle to launch a windows .exe from anywhere on my computer, it would only actually work properly if I first move the exe into the virtual drive - which deep inside a confusing directory structure. (The "troubleshooting" menu option goes directly into talking about this issue; but even finding that menu option isn't totally straight forward, especially if you're just launching the exe from a file browser or something.)

Anyway, the upshot is that I like bottles; because it is easy to use but also very transparent about how it works and what it is doing, which I like. But I wouldn't say it's the best option for everyone.
