Imperial Ambitions is a free print-and-play board game of spaceship combat with both a strategic and tactical element. The author writes:
The game is played in two parts, on two different maps. The Strategic Game is played only on the strategic map, and the Tactical Game, where battles are fought, is played only on the tactical battle maps. In the Strategic Game, units move from one star system to another, and construction, repairs and various economic functions are conducted. At the end of the Strategic Sequence of Play, any hexes containing opposing units on the strategic map may trigger a battle (at the discretion of either one of the players with forces in the same hex), at which point each battle is resolved on a tactical map using the Tactical Game
