unlimited possibilities to expand the game scope through a tech tree: - Hyperthreading - interrupts - compressed main memory - L3 caches - TLB caches - CFS - cgroups - TSO/GSO - performance / efficiency cores - dynamic clock speed - thermals - PCI bandwidth / lanes - ...

Game could start with a single CPU and 2-3 processes and then all this comes on top step by step and you can automate it away through tech tree.
