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.

Trijam is a recurring game jam on itch.io where you have to make something playable (and fun!) in only 3 hours! https://trijam.itch.io/
