Solar Empire

Solar Empire is an American collectible card game built around space warfare and solar system conflict. Designed for two players, the game uses cards representing spaceships, planets, and special effects. Play begins with planets set face-up on the table while ship and special-effects cards are placed face-down, and the goal is to capture all of the opponent's planets before exhausting one's own deck. Sessions typically last 30 to 60 minutes depending on the number of planets in play. The game is listed in BoardGameGeek's database but carries no credited publisher in available records, and the absence of a documented commercial publisher suggests it may have been a self-published or small-press project. No release date, designer attribution, or card count appears in surviving documentation. Solar Empire falls squarely into the category of games where the design concept is clear but the surrounding publication history has not been preserved.
