Maybe you could do “Developing Simulator”. Basically, you start off with a budget of 100 robux and you can hire builders, scripter, etc. for a certain amount. It will take around 15 seconds to make games. You can release these games and based on the amount of robux you made, you can level up the builders and scripters. Then when they make better games, you get more robux to hire even more workers. and then you can prestige or rebirth and start off with 1k robux instead of just 100. Rebirthing will give you faster game making time. (from 15 seconds to 14) and it keeps going lower everytime you rebirth. You need to upload like 1k videos to rebirth. And when you level up the builders and scripters, the game making time will be faster.
(sorry if this is wordy I kinda just went along with what was in my head)
To sum it up, you hire workers to make games. You can level them up. And try to rebirth and hit the leaderboard.
