I can imagine that "There Is No Spoon" (finish the game in 8 hours) will be difficult to achieve with the expansion. Additionally, I can imagine the addition of a new achievement to finish the game in a different number of hours with the expansion enabled. So perhaps some achievements could be conditional based on which "base-mods" are enabled? And for some other achievements, like "Watch Your Step", this does not matter.
If nothing is known about it yet, that's also fine, just curious
