If you haven't, give Desert Stalker a try. The reviews and trailers looked stellar so I bit the bullet and got it on steam. It's on early access, so fingers crossed it gets finished in my lifetime. My reason was "it's on steam so it's gonna get finished"..lol.
But I really, really loved the lore on the game. Ancient Egypt theme with some high tech, fallen civilization, pretty ladies... checks a lot of boxes for me.
And if it ever gets finished (apparently it has been going on for years, but I only discovered it recently) Porn Empire is a nice business simulator game. IMO some aspects are a bit unbalanced, but maybe someone else might think differently.
