Infinite Space for Sins of a Solar Empire: Rebellion. The mod enhances the overal look and feel of the game by adding a ton of new planets and planet types, planet bonuses, rendering, tweaks and much more!
I really enjoyed this map especially the SOL map too. I spent hours playing games as though I were humanity fighting some terrible alien armada in our solar system. Although I wish whoever made this would make an updated version for the latest patch and dlc!
