Sins of a Solar Empire: Rebellion Mod - Enhanced 4X v1.74

Combat will still be the center point of the game, but players will find that the non-combat options available will be much more rewarding. Spying, exploring, sabotage, diplomacy, culture, and economic development have all been added or changed in innovative new ways. Regardless of what you think Sins is, this is the 4XRTS it should have been.
This mod seeks to give more depth to the 3Xs besides extermination by adding additional game elements or refining the existing ones to reward players who give more strategic thought to the non-combat side of the game.
