I will report back how useful they are, but i don't intend to use them all it gets kinda laggy when you have so many on FRD - besides they do cost energy (1330 cost 133300 energy) the only reason i can sustain them at the moment is that i have a Zenith power generator and still building up fleet
Here is the save, kadiloc is where the fun is at (they are self-propagating for now).
I think you should come up with a way to reduce numbers that is useful to the player, ie - give shredders a 50% resource backflow when scrapping them, instead of 10% - that way the player could harvest resources directly from the enemy (how is that for an awesome idea?)
I think the replicator cap should be at 1000 though - they are still massively powerful against starships but a large amount of defenses can wipe them out.
Starting with 1000 it became a bit laggy on that world
If you let it run you could reach infinity.. technically at least
And speaking of that, maybe ramp up energy cost to 200 so its not as easy
Maybe its because i am on 200% + Handicap (yeah yeah, after restarting i want more action faster ,p)
