I will also say that Sins of a Solar Empire has the most mods (several are a lot better than the base game), although GalCiv3 is intended in the long run to have a crapload of mods and both Sins of a Solar Empire and Endless Space are basically done (Endless Space 2 is in production at the moment) whereas GalCiv3 is early in development. In general GalCiv3 will probably turn out to be a better game than Endless Space, but I have a soft spot for Endless Space whereas GalCiv3 hasn't worked out all the rough spots (particularly the AI in GalCiv3 is pretty bad at the moment, and certain elements aren't as developed as its predecessor).Įndless Space is the most interesting when it comes to exploration and colonization (although conversely the combat is rather repetitive and there isn't much graphical variety), Sins of a Solar Empire is the best in terms of combat, and GalCiv3 has a ton of content designed around creating custom ships, factions, and maps, as well as being the best in terms of politics and a lot larger scale than the other two. I will say that of the three, Sins of a Solar Empire is very different from the other two in that it plays more like an RTS than a strategy game aka the goal throughout is just killing everything.
