1. I'd personally like to see if some multi-classing would be possible.
Having experimented with the TITS editor, I found that some of the most ridiculous builds can be made right off the bat. Level 3 Tech Specialist allows for ridiculously high shields and increased damage output. Then you include level 7 Mercenary, and what you end up getting is a Steele that can easily annihilate armies, and if they're immediately attacked by any newcomers that get into the fight (see the multi-enemy fight in Myrellion War Queen quest, or Urbolg's fight.), they pop their B.D.S. in a crowd of sexable hostiles and use the orgy as a meat shield. They regen their shields (which they can apparently do in a in-game minute), and it is basically back to square one; plus the Second Wind ability just in case HP somehow makes it to less than half of the maximum.
2. I'd like to suggest an expansion on Ramis to include training for Aim stat boosting. She already enables increasing 3 different stats, why not an extra one? The level up already covers the aim bit, and even getting just a few days of training from Ramis allows you to have max stats before you walk into Zheng Shi (unless you are speedrunning).
3. Include some more consequences, and a sort of Stress stat for Steele. I feel as if a Steele walking around as a Frostwyrm and proclaiming they've mated with a Frostwyrm willingly is bound to draw some attention, and maybe even prevent a "Ruler of Uveto" ending if Steele makes it too much public knowledge. Steph Irson fucking a Frostwyrm live was already pushing the questionability of the Frostwyrm's sapience; Steele walking around as a Frostwyrm (potentially as the only one doing so because becoming a Frostwyrm usually costs as much as Paige's eyes) will draw a lot of attention to the species and potentially kick off the taking of Uveto without Steele's involvement; and therefore rights to spoils. I'd also like an actual sort of hidden timer in regards to the rival (or at least a reason as to why the rival is as lazy as Steele is, but the moment Steele gets arrested on Canadia despite having multiple live pregnancies mostly lasting up to at least a year of Nursery, Steele gives up the fortune when there's still Uveto to take.), but as the game is largely unfinished, I do understand it as it is.
A Stress Stat however, as others have pointed out in Steele not being very responsive to a lot of things that'd normally be traumatic to even hear/witness/experience, would definitely be a nice thing to have. Not only would it lead to some interesting builds, but it'd open up some new opportunities. I've always liked to play as the "perfect virgin" Captain Steele Tech Specialist, doing everything she can to help others, but taking Kiro's approach to her vaginal virginity. I also think it'd be kinda haunting if Steele failed to stop two (technically three) destinations from exploding. I'd like some nightmares about the destruction of Tarkus/Myrellion that'd appear if Steele was borderline Kind in their alignment score when making some of these decisions; the Myrellion bit especially. Unknowingly condemning a planet to nuclear warfare (and potentially killing some of the bearers/sires of your children in the process) would give anyone nightmares.
4. If there is no mention of Disney when interacting with the Rat Raiders' leader, my disappointment will be immeasurable and my day will be ruined.
5. Include pregnancy benefits for some pregnancies. I feel as if being pregnant with Frostwyrm eggs should allow some form of psychic resistance and/or immunity, as they sense their host being attacked by psychic elements. Psionic resistance is already granted by the starter clothes, for instance, so why not Frostwyrm pregnancies? Gryvain pregnancy alone causes your lacation to become Strawberry-flavored, which is worth more creds in Breedwell.
6. Expand the Mhen'ga Vanae already. We have uplifted Vanae and have sub-species to them, why can't I have a Vanae daughter in the nursery? Moreover, where is the Vanae Matrons and Queens, whose milk are so potent that they turn others into a writhing mess? Synthetic Sap was a nice expansion, sure, but the Vanae don't even react to you being a "male" Vanae, or you being one of their own.
7. Speaking of the Nursery, while I get we're busybodies both in-game and IRL, can't we get an idle function to name the children without requiring certain NPCs? Or at the very least, have their names randomly generated? Surely some lists can be pulled and re-fitted appropriately, and I could understand not caring the slightest in regards to naming over 1,000 children with appropriate names. I do, however, want to name each of my Zil children after every word in the Bee Movie script individually.
8. Ship fight with Shizuya's ship. If you've got a ship from Myrellion that has more than 4,000 shields, or you have Sidewinder, instead of being forced into a accepted cutscene, duke it out with Shizuya's ship. Not much should change besides Shizuya acknowledging your ship's superior strength; or at least Shizuya finding it strange that her supposed target has a ship as strong, if not stronger than her, and not being immediately suspicious.
