Can you focus on the original topic please? The original topic is far from "can I bang it?" or ethics behind sex with aliens. The original topic is about an alien species similar to Xenomorphs using host dna for hybrids and infiltration. Some what similar to how Driven assimilators turn captured pops into cyborgs.
It is best to ignore him overall. He seems to be doing the kind of trolling where he just narrowly avoids violating any obvious rules.
To your original idea, there are two (3) parts however:
- Infiltration, wich would be a Espionage mechanic
- unlocking Xeno Compatibility as a species trait (aka the Asari way)
- genestealing
Infiltration has to wait until we got a Espionage thing that is better then "Criminal Syndicate Megacorp".
With
Genestealing I have no idea what that could even mean from game mechanics.
Xeno Compatibility via trait (the Asari way) might be worthwhile. They are interesting in that their Xeno Compatibility is one way only. The result will always be a Asari + half other.
Their way to make halflings could be simply a outrighz copy of the traits, in a Asari Shell (as a Subspecies of Asari). So it does not have the downsides of adding a lot of Xeno Subspecies to your Empire.
Here is the relevant part from the Rules section:
Code:
# This = planet
can_crossbreed_species_on_planet = {
exists = owner
owner = { has_ascension_perk = ap_xeno_compatibility }
count_species = {
limit = {
is_crossbreeding_possible = yes
}
count >= 2
}
}
# This = species one
# Root = species two
can_crossbreed_species = {
is_crossbreeding_possible = yes
root = { is_crossbreeding_possible = yes }
}
The scripted trigger seems to be only about excluding edge cases:
Code:
is_crossbreeding_possible = {
is_sapient = yes
NOR = {
has_trait = trait_machine_unit
has_trait = trait_mechanical
has_trait = trait_hive_mind
has_trait = trait_self_modified
}
}
The actuall creation of the subspecies seems to be done via non-modable code. but it should be possible to rig up some event that has similar gameplay effects.
