Windows Looking for a good game (Immersive sim)

I agree that F:NV is the next one you should try, and I'm also a big fan of Kingdom Come: Deliverance, I think it's simply fantastic and a real underrated gem. I'm not sure that the Mass Effect Trilogy has been mentioned in this thread already - if not, those games are great! Another less popular one that deserves more eyes on it is The Forgotten City
