The Matrix has 7 simulation games on file for the Intellivision, released between 1979–1986. 2 of them support multiplayer. They're ranked below by legacy score, so the games that shaped the genre on the Intellivision come first, with lesser-known picks further down.
Simulation games model a system and let you play inside it, whether that means building a city, flying a plane, raising a pet or running a business.
Typical commitment: weekend project (roughly 6–20 hours). Tip: Simulations are often open-ended. Set yourself small goals and enjoy experimenting with the systems.
