Sadly with The Talos Principle 2 they moved their entire studio to the Unreal Engine 5 and retired their own engine in the process. Apparently they lost a few engineers working on the engine and also couldn’t have kept up with modern engines without some serious investment (no pun intended). On one hand it’s probably for the better as we got a really pretty game where they could focus more on the game instead of bringing the engine up to speed but it’s also sad to see the entire industry converge around engines like Unreal.

A great game I haven’t seen mentioned yet is The Talos Principle (1) that also has a really good native port using Croteams Serious Engine.

Personally I deactivated pre-caching quite recently actually as I noticed as well this getting quite excessive for certain games. So I now wait until this is a thing: https://github.com/ValveSoftware/steam-for-linux/issues/6486 Seemingly the issue seems to be with games that have a big workshop like A Hat in Time or just huge games like No Man’s Sky. I got 10GB and 5GB shader cache updates daily for these games respectively before I turned it off.

GOG only distributes the Windows versions sadly.

Metro 2033 Redux and Last Light Original and Redux have Linux native versions on Steam already, just not the original 2033. Granted, the original games are not even purchasable anymore though, only Redux.
