# SIMNET **Domain:** Military simulation **Doc Type:** Developed System Node **Maturity:** Developed **Collection:** [[collections/Gamification|Gamification Collection]] ## Definition **SIMNET** (Simulator Networking) was a U.S. Department of Defense program begun in the 1980s to network geographically distributed vehicle simulators in a shared virtual battlefield. It demonstrated that many relatively inexpensive simulators could inhabit one persistent exercise rather than relying only on isolated, high-fidelity devices. ## Significance [[articles/gamification/America Loves Games and the Home Court Advantage|America Loves Games and the Home Court Advantage]] places SIMNET in the longer American sequence from instrumented play to shared synthetic terrain. Its critical innovation was not visual realism alone but the construction of a [[wiki/Common Virtual Environment|common virtual environment]] in which many participants could act on compatible state. SIMNET is a material ancestor of networked virtual worlds and distributed military training. It joins interoperability, common state, real-time adjudication, and embodied control—the technical substrate through which a simulated contest can become an institutionally consequential exercise. ## Sources - National Research Council, [Modeling and Simulation: Linking Entertainment and Defense](https://nap.nationalacademies.org/catalog/5830/modeling-and-simulation-linking-entertainment-and-defense) ## Routes [[wiki/Military-Entertainment Complex|Military-Entertainment Complex]] · [[wiki/Institute for Creative Technologies|Institute for Creative Technologies]] · [[wiki/Kriegsspiel|Kriegsspiel]]
