sounds like Mr. Wallet's Rise Of Blockland thing
A good example of a tycoon from roblox would've been any "brick tycoon"
Basically a brick drops a projectile onto a conveyer belt which leads to a brick that detects the projectile, deletes it and increases the number of money you have. You then spend money on upgrades such as projectiles spawning faster, more often or more than one at a time, the conveyer belt moving the projectile faster, having the projectile increase your money more and whatnot.
Also there was this one server where you would have a team in a factory, and you're tasked with creating, loading and shipping hats.
One team loads the conveyer belt with raw materials, which get turned into hats. The hats are then moved on down to a bin where another team is tasked with loading the hats onto a vehicle, and then driving it to a delivery point, and dumping the hats there. Then, as the hats are produced, the factory gets "dirtier" (aka spots of dirt, darkened windows, clogs in the machines), halting progress by slowing down the process of making the hats, or making the players receive less money per hat.
Both things would be cool in blockland, but I can imagine them being easily evented.
