Woe is I ... I can understand the issues with space (unbalanced, interface, off planet) but I don't think any Civgame without space (now that it has been introduced once at least) will ever be complete again ...
This version of Civ is too yummy to pass up - AI, Diplomacy, graphics - but it lacks that last step - space.
Who do I have to arm-wrestle to get space put back in as an expansion ...
I don't miss the space aspect of the game, but mostly because of it's poor implementation in the original.
I do like the thought of oribital colonies, space combat, lasers hitting national statesmen while they are sitting on the toilet, etc.. I have been really hoping to see moon colonies in a CIV style game, but my opinion of that depends on if developers can implement it well.
