I know of a few mods which would do well with SoGE; Sins Plus - always a good idea Dynamic Battle System (From the Last Stand mod) - Cause it is really cool, makes certain ships fight like fighters Celestial Bodies mod - multiple planet sizes as well as more star types RealCapitalShips - Cause capital ships need more power Some mods have features which would be neat to replicate; Distant Stars - Many more tech levels, and more capital ships Mad Scientist - More tech levels, more capital ships, and also tech trees to increase weapon rates of fire The various engine upgrade mods are also good, like Gurkoz sound mod and the Volumetric effects mod. I cant remember if SoGE has these already or not, but even if not these are available as stand-alones which can be integrated additionally by the game.
