you sadly missed a civ building steam sale which the tab alone helps in finding games.

ill recommend rimworld, against the storm, anno, kingdom two crowns, kenshi, warhammer 2

look into modded campaigns for fallout 3/4/new vegas, skyrim etc.

just browse sales and pick games you like, try new things, get gamepass.

I'm playing through ff13 with modded graphics and my mp games i'm playing terraria modded, risk of rain 2. there are too many games to play, I have gamepass but I havent even started a lot of them.
