Engine-Builder
An engine is any collection of pieces that each have a job/role working together to handle some process from start to finish.
Engine-Building falls very squarely in the broader strategy group. These are fun because you typically have all the options in the world. It is up to you to choose the right path to victory. This doesn’t have to be the only game mechanic in a game. An engine can be both major and subtle, but it is never half-assed. A good engine takes lots of intricate pieces working together masterfully. If it is not well put together it will fall apart, no matter how big or how small. It is always working towards a greater goal as well, like a big victory.
Examples: Century, Wingspan, Terraforming mars
