idk if ksp 2 will get dlc or not, but it's worthy to add all dlc parts from ksp 1 into base ksp 2 since the game is more expensive than ksp 1 complete edition.

Yeah, I agree on the various DLC functionality being added, or at least all that was popular.
Considering all the parts are popular they should add those.
They should also consider adding functionally similar parts to the many popular mod parts.
