Work at a Pizza Place
The Grand Theft Auto V of Roblox.

Created by Roblox user dued1 in March of 2008, this game is exactly what it sounds like; and it has withstood the test of time quite well despite its simplistic concept and overall decline in quality since 2017. Nowadays, dued1 doesn't really "update" the game anymore; he just adds stuff without fixing problems that have existed in the game for years.

In other words, he's milking it. Just like how Rockstar is milking Grand Theft Auto V.
