itch.io

Games that try to simulate real-world activities (like driving vehicles or living the life of someone else) with as much realism as possible. Simulators generally require more study and orientation than arcade games, and the best simulators are also educational.

Software produced for proprietary consoles by reverse engineers, hobbyists, and more. Often targeting retro & alternative devices.
