Roblox Miners Haven / Lumber Tycoon 2 as a S&Box game.
Early Development, fully playable, a little glitchy when moving many items around, but thats basically what you expect if you've played the Roblox games.
Can easily sink your teeth into this with a bunch of time, goofing around, experimenting, and trying to build big conveying machines that'll earn a lot of money.
Give it a shot, Take the bad reviews with a grain of salt, most people can't handle bugs, its not that bad.
