Subsim is the media outlet for game publishers that feature naval content, a resource for military strategists, as well as a source of editorial comment on the state of PC computer simulations and games. Subsim members have been consultants and testers for game such as Enigma, Silent Hunter II, Silent Hunter III, Dangerous Waters, Sub Command, Fleet Command, Destroyer Command, among others. Shortly after the release of the ill-fated Silent Hunter II, Ubisoft agreed to provide Subsim with the game source code to replace the rTime multiplayer engine with DirectPlay. Subsim members raised $10,000 to pay a programmer to make the improvements.
