Yes, I'm quite late to the party - but I thought I'd give Luyten a whirl for
this month's screenshot contest 
A few story decisions (like the sacrifice of a destroyer - how many do they have?) seemed a little odd to me; the music was, eh, not what I would have chosen; many of the custom ships show their age.
But! The overall gameplay experience was immensely enjoyable. There's a tremendous variation in mission types, way beyond the usual attack/escort/space-superiority roles. And it is all very well executed, giving a great new spin to our beloved old space sim. My single favourite part was...
The kamikaze drones. They were a joy to fly, nimble enough to evade most enemy fire - and all the while, not having to worry about hull integrity or firing back. It was great!
A few small bugs I ran into: after "The Duel", I got the debriefing-that-I-shouldn't-be-getting; and the very last cutscene lacks starfield.pof.
Overall, despite a few rough edges, Luyten Civil War was an innovative campaign which I thoroughly enjoyed playing!
