For the last few months, I’ve been playing 7 Days to Die with my friends. It’s pretty wild, but it has appeal. There really isn’t an end to it. You can play it for a long time. And the Minecraft-style building is pretty entertaining.
You can play it by yourself if you’re fine with no real goal but just to survive as long as you can. But it’s more fun when you have others to play with. Just beware, don’t play on their servers because they’re slow. Get a private one, it’s not expensive. My friends and I rent one from https://7d2d.net/ for only $6, so I recommend getting one from there.
