I remember yesterday thinking that if I was ever a game dev, I would make a zombie game where the setting is in an open-world city or a small town with zombies roaming the street and homes, and really the most you can do is hide, kinda like amnesia, but sometimes you'd find things like a bat or knife, but they'd barely do really any damage at all but push back or hurt the zombies for a bit, and a gun would be the rarest of them all, while there's also a hunger, thirst, and temperature system, depending on the season that's randomly picked for the game, and rain would effect the temp. system too, while there'd also be some cars/vans in the streets, vans mostly having supplies, like food and liquid, and there'd be enterable buildings, but there would be two or four zombies in the places, but rarely, and you'd be able to raid fridges and all, but the main thing in the game is to hide.
Now, onto the topic, project zomboid seems to be your type.
