Eco, as you mentioned, is very much like what you describe, but it’s not a shooter if that’s a requirement to you. It’s not much like Minecraft, I’d say the only real thing they have in common is that things are in blocks. Other than that it’s wildly different games.

If you can find a good server or you have a bunch of friends who also want to play like this, you can get a very fun experience. But you need to all be into it and playing for the social aspects of the game.
