We can only control whether the barb player gets them at all; we cannot allow the barb player to have them but force them to spawn later.
I'm aware. But you *could* if you wanted take them away from barbarians, and then create a similar unit that was buildable only by the barbarian player but tie it to a later tech.
Which would have the same effect.
You can only get a list of the units they *cannot* get
Fine, same thing, I will take a look at some point. Is there a distinction between which units they can build in their cities, and which units they can spawn in fog of war?
Do you really want to link "worms don't attack" with "barbs don't attack"?
No, not particularly, but *if* you wanted to make it so that Fremen were immune to normal barbarians (which was the proposal) then I would say you shouldn't try to *undo* that by making them vulnerable to worms (by making the worms hidden nationality).
It would be very weird if Fremen were at peace with on-land barbarian smugglers, but could still be attacked by sandworms.
I don't see a strong need to make Fremen at peace with on-land barbarians, so that leaves you free to use Thumpers to effect their interaction with Worms.
Doesn't the barbarian world option normally start the game with barbarian cities?
We should think in general about the role of barbarians and how important they should be. I definitely don't think we should go as far as Fall Further, where barbarians are very powerful and often wipe out AIs, or hamper their growth, making the AIs a pushover. Powerful non-House/state actors don't make that much sense in a Dune setting I think.
Its not like smugglers/"feral" Fremen really pose much of a military threat to anyone.
But it would be nice if barbs were enough to at least hamper initial expansion. We could also think of the barbs as the Houses Minor, gradually getting eaten up by the Majors.
DV21: The Firefly unit is missing from the unit upgrade path I think. It looks like it should slot in between Wasp and Locust.
Fighters and bombers should upgrade differently. I forget the names, but I think we have 3 fighters, a bomber and a stealth bomber?
IIRC the Wasp and Locust are both fighters; the Firefly is a bomber. So we should not have wasp -> firefly or firefly -> locust.
Also, is it correct that Grenade Trooper upgrades to Shield Fighter?
No, it should upgrade to a heavy trooper.
