Indie Developer Taitale updates their Kickstarter for Novus AEterno today with new info on how planet alteration and terra-forming occurs in their MMORTS.
Players will be able to graphically as well as statistically change planets in their control including Epic Planets. Current achievements and sectors on these planets will be unchanged but debuffs and stats will be impacted. There won't be any unique terra-forming for the purpose of balance.
The full explanation and a lengthy Q&A video can be found on the update page.
