You guys should know Surviving Mars base game is free on steam right nowhttps://store.steampowered.com/app/464920/Surviving_Mars/
It's paradox, so they likely make up for it with DLC sales. However all the paradox games I've played with their native linux builds have worked great.
Don't know when I will get around to playing Surviving Mars, so I can't comment on the linux binary quality of this one, but its likely good.
Grabbed that game from Epic a while back when they ran a free run of it, but haven't installed or tried it yet, but will get around to doing that.
Found out Epic gives a way a game a month so have been grabbing one here and there when they did, so can recommend installing the Epic store app too to get notifications when they do.
The epic game store is not worth it if they payed you to use it.
I would say its literally hitler, but I think that would flag the wrong ideas here. kek
