Star Ruler 2
Star Ruler 2 is the sequel to the ambitious space 4X Star Ruler by Blind Mind Studios. This game has several concepts not seen in many other 4X games, such as leveling up planets and the lack of colony ships. Winning the game involves either conquering all of your foes, or having them join you, and diplomacy is conducted by a series of ability carts. Overall, there's a lot here.
Concept
Take control of one of many races and, through exploration, resource management and combat, conquer the galaxy on section at a time.
