From Wikipedia Air Warrior was a multiplayer on-line air-combat simulator launched by Kesmai in 1988. It was hosted on GEnie and used that service as a server for client software running on a variety of personal computers available in that era. It underwent continual improvement through its decade-long lifetime with Kesmai, appearing on new platforms and host services. ... Air Warrior was played over modems and hosted on the GEnie online service provider. Players could choose one of a number of World War II aircraft to fly, along with ground vehicles, and play in a multiplayer "arena" with hundreds of other players. The game focused mostly on dogfighting, with a secondary strategic role of capturing forward airbases near the center of the map. Several updated versions were released, and additional service providers were added over time.
