9. Star Trek: Starfleet Command (1999)
Starfleet Command, a starship-based operations and combat game, successfully adapted the popular Star Fleet Battles board game and, as a result, brought the genre to a much broader audience. Players can join the fight on any one of six sides, including obvious choices such Federation, Klingon, and Romulan, as well as more mysterious options like the Gorn, Hyrdran Kingdom, and Lyran Star Empire.
Players can embark upon a solo campaign, in which they earn skills and accolades during missions that can be used to upgrade their ship and crew, fight quick skirmishes, or battle friends in groundbreaking multiplayer contests. Gameplay was complicated and demanding, with players forced to manage shields, weapons, crew, and unique special abilities all while in the heat of combat. For those who mastered the mechanics, however, Starfleet Command offered a rewarding experience for countless ship captains.
The game, and its sequels, spawned a huge community that produced countless mods and enhancements, making the Starfleet Command series still enjoyable and playable even today.
