Just picked up David Weber and Steve White's books, Crusade, In Death Ground...
So far pretty GalCiv like save for the FTL style.
Actually, the entire Weber / White collaborative series is based on the senarios (literally, straight out of the back of the rulebooks) of a space war game called Starfire. David Weber was the Re-Editor of the 2nd Edition (the edition that really cleaned up and reached playability) of those rules about 2 decades+ ago.
Incidentally, there are a couple of historical threads in that game melieu, well after the 3rd Interstellar War (Bug War), that would make a fine pair or trilogy of novels. In particular, there is a thread about a Battlestar-type (but more numerous) fleet of refugees from a VERY advanced but Very Regimented humanoid society. There are First Contact misunderstandings, and of course they are also being distantly pursued by their home Civ, to be 'brought back into the fold', ala Wells "1984".
If you look carefully, you can also see the bones of the Starfire game in the mechanics of the Honor Harrington universe, but DW has put many years of subsequent mulling into refining the explanations of how a 'sub-light tactics, FTL strategy' society may be rationalized.
OK, just thoroughly ID'd myself as geezer space gamer, but then I guess that puts me in company with...David Weber. Not a bad galaxy to hyper around in.
