[Mylon]

Yes, I appreciate the idea of not being able to make homeworld clones easily, but I would like to see making such clones actually possible to some degree. The value improvement plants are in themselves terraforming facilities that adjust gravity, temperature, some air conditions, ect. (and there have been plenty of times when my homeworld has been generated with "unpleasant" conditions).

Still, 500 turns for a race that specializes in fast building (hardy industrialist + 20% space yard rate) is a tad much. 50 turns (5 years!) may seem too short for the description, but that is plenty long building time for one facility and I really doubt that anyone could realistically build more than 3 on any particular planet. And this also makes upgrading them actually possible, if we ever get the ability to upgrade one facility at a time and more levels are added.
