I tried playing with the new science packs, and they feel kinda shoehorned in, given the fact that most of the planets already have a science. I think it might be worth making an option to not add the science? I also say this due to the fact that it adds science pack bloat, maybe the last one makes sense more but i think the intermediates might be enough to have an impact? This is just my 2 cents.

To add to this, I did have 2 playthoughs, 1 that was on going that I downgraded back to 1.9.1 and one started fresh, I am referring to the fresh one primarily.

I wont add that option itd mean rebinding the entire science tree and thats too much of an hassle. Just accept their existance theyre here to stay
