Having fun, great game, if it feels a bit stripped down from Gal Civ 1, at least from a technology standpoint.
Also, can't wait til the tables are back in the game, the diplomacy interface is... less than it was.
On to a few questions, not really intending to be answered, so much as to point out what I feel is missing.
You touch on the Oort cloud in a planetary event... where is it?
Where is Halley's comet, or the Jupiter family of comets?
When can we mine them... after all, this has been a big deal for humanity since about 1750.
Where is the interstellar ice, and when can we start mining it?
If planets are composed of coalescing nebula dust, as per Carl Sagan, when can we mine it for the raw materials present, and to clean up our space?
Ditto for asteroids?
When can we move planets to their optimal distance from stellar bodies, to support life?
Can we see the optimal distance band, in some fashion?
When can we obliterate troublesome planets that we feel aren't worth the trouble to terraform, particularly with an eye to building 30 superworlds that require massive amounts of raw materials?
When can we build useful stars?
Can we not return massive amounts of ... ice/rock/dust/etc... to improve our worlds?
I have a slightly different take on terraforming; imagine you could select a level of terraforming, and be told how much of what specific material was required to accomplish the task of upgrading a world from level x to level y. Bands of tiles would appear, colour-coded for levels of terraforming difficulty, when you open the terraforming tool; this would allow you to view how the planet would turn out. Further upgrades to the system would allow you to move the planet to the optimal distance from its star, add water to tweak humidity and atmosphere, and finally, add planets together to create superworlds.
Maybe I'm just tossing out stuff for Gal Civ 4.
I'll back it. Just say when.
