NPC Hospital, where you’re a doctor and have to deal with the massive body counts from other games.
Or a foraging game, open world style, where you have to travel to the right places during the right time of day to pick certain foods. There are lookalikes and also tons of risks like landowners with guns, pesticides, snakes, and tough terrain. I imagine it would be very much like The Hunter COTW but with plants.
Dune: Universe.
A Build Engine(Duke3D, Ion Furry) or Build Engine style(Cultic) game made around Petey Wheatstraw/Blaxploitation film genre. The “Holly Trinity” of Build Engine games were based on action films, each with their own specific flavor. Duke3D was 80’s action, Shadow Warrior was badly dubbed HongKong Action and Blood was westerns and horror.
Blood and Cultic both have robbed cultist that light up real good with a molotov cocktail. I think it would be incredibly satisfying to light up KKK members the same way.
A Blaxploitation game would be rude, crude, and upset a lot of people. It could also be really fun and something that hasn’t been done before. Most games that try to tackle racism do it was an attempt at nuanced or preachy writing. I just want to beat a neo-nazi with my pimp cane.
I’d play the hell out of that.
I forgot to mention the One Liners that are in Build Engine style games. I think Cultic is the only one with a silent protagonist, but that was Film Noir/Lovecraft Horror, so it’s excusable. One liners like this would fit so well with that style.
