there's this game called "Fleet Command" released around 1999
https://en.wikipedia.org/wiki/Fleet_CommandFleet Command, previously labelled as Jane's Fleet Command, is a real-time tactics naval warfare simulation computer game released in May 1999.[1] It was developed by Sonalysts Inc. and published by Electronic Arts (EA). The game licensed parts of Jane's Information Group's military information database, which was used as an in-game "Jane's Library", reference material that the player could refer to while in-game. Jane's also licensed to EA the "Jane's" name and the "Jane's Combat Simulations" logo, and the game was marketed under the "Jane's" name, much like the previous "Jane's Fighters Anthology", also published by Electronic Arts.
it can be a single player or multi-player.
released for PC, 1 CD/DVD for install and update
later on it can be downloaded on "STEAM" website
upon install, there was only one unit that belonged to the Philippine Navy, that was the Bacolod Class
later on there was a software where you can modify/add/subtract units to the game,
some die hard players who have the a 3D software that can create/modify the 3D files of the game made and added units to it (some boats that was not on the initial list of ships that can be played)
you can also create scenarios, there are already some scenarios included but you can also modify those
it is mostly about naval tactics but you can also add air force units and army ground units in it but are limited, especially the ground units
i still play the game sometimes,
