Maybe sorting out what is "personality" and what is "additional feature" would be helpful. I'm going to browse the
list and see what can be done on the paper.
Bouncer: replace wormhole guard posts by regular ones? Can be a plot. Easily.
Chivalric: don't got for irreplaceable targets. Sound like a personality, but as long as it only affect "eligible target" checking, maybe it could be a plot (a kind plot... strange. Maybe a modifier like schizophrenic or no-wave)
Cowardly: don't engage unless superior. Same as Chivalric, personality but only influence a precise point in AI internal calculations. So rather an AI modifier than a plot.
Entrenched Homeworlder: captive human settlements, it's just adding buildings, so it could be a plot (looks like a minor faction, something like rebelling colonies in less dramatical proportions, risk/reward capturables)
Fortress Baron: fortresses more common. Buildings: can be a plot.
Grav driller: buildings; can be a plot (and risk/reward too)
Mine enthusiast: buildings (sort of); can be a plot.
Neinzul Viral Enthusiast: buildings; can be a plot. (I'm going to copy-past it...)
Shield Ninny: buildings; can be a plot.
Sledge hammer: Oh, something new. Waves are half as frequent but twice as strong. Tweak waves delay and strength. Some "half waves" or "cross planet waves" AI modifiers already exist and it looks like that.
Support Corps: Extra unlocks (there could be some "packs" of unlocks that would be useful for youngsters, zenith descendant, spirelings and the like) and no wave.
The Tank: extra unlocks and tweak waves strength/reinforcement.
Train Master: sounds like advanced hybrids for trains. A plot with an advanced version already exist. And the normal train plot intensity tweak which kind of nasty trains could be used; it would be interesting to be able to tweak quantity apart.
Turtle: no wave but extra reinforcement? Sounds like preemption. And the "no wave" already exist as AI modifier.
Vanilla... seriously?
Artillerist: extra unlocks.
Assassin: this is interesting; it tweak the player target logic. Each AI could have a three-state-switch: target best player, target weakest player, normal targeting.
Backdoor hacker: sort of building, isn't it?
Bully: see assassin.
Camouflager: all ships have the zenith chameleon's ability. on/off switch like a plot.
Counter spy: buildings; can be a plot.
Exotic: this one is special. The wave definition (alongside with "no wave warning", "cross planet waves" and the like) would be complex.
Experimentalist: unlock pack.
Feeding parasite: unlock pack.
Kite Flier: sort of "everybody"s ability, like camouflager.
Mad bomber: tweak the wave/reinforcement ratio and give... extra unlock?
Neinzul cluster bomber: buildings; can be a plot.
Neinzul youngster: unlock pack. And maybe influence wave composition (see latter)
One-way doormaster: buildings; can be a plot.
Peacemaker: buildings; can be a plot.
Reservist: just a plot?
Speed racer: "everyone"s ability. (I'm going to need more than one clipboard)
Spireling: unlock pack.
Stealth master: unlock pack.
Tag Teamer: speedy guards? Wat? Well, is this one an ability-like?
Teleporter turtle: unlock pack.
Thief: unlock pack.
Vicious raider: unlock pack and wave/reinforcement balance tweaking.
Zenith descendant: unlock pack.
Alarmist: buildings; can be a plot.
Attritioner: buildings; can be a plot.
Everything: unlock pack (kinda special pack)
Extreme raider: unlock pack
Fortress king: modular fortress command station? Wat? Well, does something else modify command stations? yep, the "subcom" personality, but it's a future one
Golemite: sounds like a plot. Anyway, it's something added (a bit like buildings)
Mime: modify wave composition. Incompatible with AI that change wave composition too.
Neinzul nester: buildings; can be a plot.
Overreactive: tweak salvage/reprisal calculations.
Quadratic: tweak delay/strength of waves.
Radar jammer: buildings; can be a plot.
Retaliatory: counter guard posts... don't know how to handle this exactly.
Scorched earth: sounds like a plot, like "atomic command station" (thematic), or the Avenger plot.
Shadow master: unlock pack and "buildings; can be a plot."
Special forces captain: only has special forces guard posts, which tweak guard post pick (like bouncer or retaliatory)
Spire Hammer: special unlock pack.
Starfleet commander: change the composition of waves.
Starfleet fanatic: change the composition of... well, everything that move.
Vanguard: same thing.
Vengeful: trigger exowave when... whatever happens. Sounds like a plot.
Vorpal: extra unlocks? wave delay/strength? don't understand.
Warp jumper: ability for everyone, and can the absence of warp gates count as some sort of building [not] seeded?
Brutal: core guard posts, so influence guard post pick (like bouncer, retaliatory and special forces captain)
Crafty spire: sounds like golemite.
Heroic: extra unlocks or wave composition modifier?
Raid engine: buildings; can be a plot.
Technologist homeworlder: already a dual type; like homeworlder (buildings; can be a plot.) but Mk+2.
Technologist Parasite: extra unlock and Mk+2.
Technologist raider: raider and Mk+2
Technologist sledge: sledge and Mk+2
Technologist turtle: turtle and Mk+2 (so obviously Mk+2 will be a separate "technologist" plot)
The Core: all ships are MkV; so change the composition of ships (waves/reinforcements/exo?) like vanguard and starfleet fanatic, right?
vicious exotic: the plot of exotic but with a big bonus to "wave" size.
Ok, I'll come back tomorrow to clean up this mess. This is an awesome idea to sort out all the AI personalities and make little compatible (or incompatible for some) plots/modifiers/MF/whatever.
Good night.
