Jeez been reading back through the thread, i can see why development has been more wonky than ever. Listening to the "community" has likely done more damage to the development than helped, especially in balance aspects and beggars.
Additionally a lot of the issues people seems to have (save files and camera for example) are engine based, something Dere would likely have to create a new version of to improve which is a MASSIVE undertaking. To make things worse the time spent attempting to update to the newer IE has been a multi month undertaking and a massive kick in the nuts.
For an example, think like minecraft version updates on mods, but 1000X deeper as its every single aspect of the game and not just a mod.
*Sigh* anyway.
From what I've seen, the only thing affecting neph generation is the world level. Traits and levels only matter insofar as they increase the world level. I think it'd be much better if you could shape the world like that, but it doesn't seem to be the case.
Well good time to test it. Gonna do a bunch of breeding and release like 10 nephs with the same Trait and see if i can find anything.
Tho logically/programming end i suspect that is the case already that it wont have an effect as it would be a massive undertaking to implement such a thing.
Edit: Yeah...
This er... might be substantial.
