20 or 30 turns after gifting "galactric expansion" to the Clukruk I have yet to see any ships or anything.
I also parked an empty troop transport above their homeworld and gave it to them (sold it for 1000 minerals

). They have yet to move it (I kind of hoped they'd go and conquer an EEE colony) but it might well be full of troops. I'll get some LR scanners later and find out.
(Oops- they're neutral - they can't attack a colony unless it's in their system! I think I'll send in a coloniser and gift them that, see what happens.)
Oh, and I met the Zynarra. I sent in a ship and saw that their homeworld had 4000 troops and 550 crappy fighters, as well as a heap of really low-tech space stations.

- This mod is great fun.
Anyway, I will probably get on with that dedicated primitive shipset soon, and then swap it out with one of the existing neutrals, so that not all neutrals will be primitive, just most of them.
Also, now that Quarian has produced the "guts" of the mod, I might start messing about with it and release my own "remix".
