Don't know what the situation is for those games since they are still in development (but I saw something about 'Linuxification' from the Camelot team), but it's much easier to run games on Linux these days than it was only a couple years ago. Main reason is something called DXVK and Wine. Don't use steam myself, but they have something similar as well called Proton. Development and funding is much better these days, partly due to what steam/valve have done (they actually deserve praise there, despite how much I dislike their philosophy and DRM 'infrastructure' otherwise). DXVK is simply fantastic news for us.
Wine has been great and all, but it hasn't been specifically focused on games, while these newer developments are.
Of course it varies from game to game, and I don't know how well these two would work, but statements like "games don't work on Linux" is much less true these days than it was. There are sites like
https://www.gamingonlinux.com/ too, with dedicated people who seem to get just about anything to run. And awesome people like
Adamhm on the GOG forums, who has made many installation scripts that does everything required with basically a click of the mouse, including the installation script I use for Civ4.
(and this is besides other awesome news like many independent game studios releasing proper Linux builds, which for some odd reason multi-billion dollar companies are unable to do...)
If you or others are intrigued by Linux and the other opportunities with it (like control of your own computer, or an operating system that isn't a resource hog), then I'd recommend to try out a dual-boot system (both Windows and Linux installed side by side). That is how I started out. Eventually I pretty much never fired up Windows, so I simply removed it. That is many years ago now, and I haven't missed it.
