Personally my favorite is the first game, but I was overall disappointed with the second game. I felt it was a somewhat dramatic step down in writing quality, and though there were some amazing set pieces, the latter half of the game felt like a bit of a slog to me.
The 3rd game has even worse writing IMO (especially the colonel’s dialog), but I was surprised that, for the most part, I enjoyed the gameplay most of the way through, and found the travelling aspect to be quite neat. I had more fun with it than the 2nd game, at least.
I also had some difficulty getting it working on my rig, and I’m not a big fan if Debian’s documentation, as it often does assume knowledge, which makes it harder to follow along and feel confident you’re doing the correct steps.
Ultimately I switched my only Nvidia system to standard Linux Mint to have access to their easy to use Nvidia driver installer, which makes upgrading or downgrading the driver a 1-click process (though it requires a third party PPA done by a canonical employee to access the latest 610 drivers).
