Rusty's Retirement is an idle farming sim from solo developer Mister Morris Games, released on 26 April 2024. Its trick is the layout: the farm docks to the bottom of your screen as a thin strip so it runs beside a browser, a code editor or a stream, and a vertical side-screen mode and a slower Focus Mode exist for people who want it even less distracting. You play a robot named Rusty who plants crops, converts them into biofuel, turns biofuel into spare parts and spends those parts on more land, more bots and more robot neighbours. There are 71 achievements and a Twitch integration that lets chat run the farm, and the game sits at 97 percent positive on Steam.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.
