Free Simulation Games

Systems you manage rather than opponents you beat. Each one models something real closely enough that the pressure comes from the model, not from a timer. Grid Operator puts you on a power dispatch desk where you can never build a new plant, only redirect what you already have. Drought Garden gives you one reservoir for a whole season and never refills it. Approach strips air traffic control back to its essence, where you do not steer aircraft by heading at all. Expect to lose the first few times and to understand why.
