I prefer the old one because having 30% of the children born in the world being 'dim' is not realistic in my opinion. I let the game play for 40 years on it's own and the sheer number of negative genetic traits seems really weird to me. Having characters be 'bright' and 'absent minded' and 'club-footed' and have 'freckles' while also being a 'burly' 'dwarf' is just too much. 20% of the population did not have a club foot as far as I'm aware.
That's why I dislike the system. I don't like paradox's system, but I also find this one to be overkill.
I'm probably going to be reverting to the previous system. There's enough variation in character skills as a result of the RNG nature of upbringings; I personally don't feel like we needed this system put in. Or at the very least add it in but maybe only keep the old traits. What purpose does 'freckles' serve as a trait? Why is the Roman Emperor a 'mastermind theologian' who is also 'dim'? IMO adding these traits wasn't needed. I hope the previous version works just as well.
Seconded. You're not alone in this matter. This Improved Genetics system is just not my cup of tea; too much micromanagement having to calculate our partner's potential traits in order to have an average offspring.
Literally no one part of the game is needed. Parts of the game just combine to add depth. If the added traits make doing what you want to do in the game harder, they're working, because a good gameplay element offers both more reward, and more difficulty.
That being said, I've already described how easy it is to revert to the old system. I've also tried to describe how hard it would be to maintain IG as a submod. Even if only a plurality of players strongly prefer the new system, integrating it would
still be the utilitarian move, because it's many times harder to submod in than submod out.
I'm happy to explain to people how to revert, but characterizing the mod as now requiring "micromanagement" to have an average kid is unfair. Reversion to the mean is literally built into the system. You will occasionally experience disappointing children, as many real parents do, but even the "dim" trait will barely affect their stats. I mean, should we be up in arms about the micromanagement required to prevent our heir from getting "slothful"? Likewise, the following is simply a mischaracterization:
At the end of the day having to worry about my offspring being 'dull' or 'club-footed' through no fault of my own is not fun for me. It personally breaks my immersion when I feel like I'm running a eugenics program in the Byzantine Empire with selective breeding. That's my opinion. Yours may vary.
EDIT: By the way; I don't know if this is a vanilla problem or not; but why can the 'dull' trait exist with the 'quick' trait? That seems very silly.
Dull, as the edit seems to acknowledge, is literally not on the genius-imbecile spectrum. It's a vanilla trait that IG doesn't touch. So, the HIP trait criticized there (1) does not come from IG and (2) is not addressed by IG at all. If you wish IG to become more comprehensive, and address that "silliness," fine, but what you're actually complaining about has nothing to do with IG.
Likewise, the prevalence of clubfoot is probably due to interaction with the vanilla pregnancy events. IG could become
more comprehensive, and address them, but it would have to become
more comprehensive to do so. HIP already has a game rule to turn these off.
But more importantly, all these critiques basically amount to: I want to be able to make marital alliances without caring about genetics.
Great! Do that! You still can!
Now, doing so just has a trade-off: if a player marries purely for lineage and land, as medieval nobles did, they run the risk of having kids who are not as impressive as their rivals - the same risk that medieval nobles ran! Hapsburg inbreeding wasn't the
only historical example of such an issue, and part of the reason Byzantine succession was competitive with other nations, despite its instability, was that it ensured a reasonably intelligent and capable ruler. Likewise, Turkish succession had benefits over Western primogeniture precisely because subtle variations in a potential ruler's intelligence and charisma
did and
do affect history.
You can
still ignore them. Now, there are some small consequences for doing so, which a human player can basically nurture into even smaller consequences. But, since even a randomly educated "slow" player ruler is superior to the AI, these consequences are mostly an RP/aesthetic issue. If that's severely bothersome, luckily, reversion to vanilla is very easy.
