I will say one thing ,,,,once EA or Activisoin, or Atari release a game ... It may get a patch ... but it certainly will not evolve much if any....
With the Gal Civs they evolve a bit over time .. the designers are not afraid to dial it in so to speak after reading all the feed back.
And some things design choices can look like a bug if you dont expect it to work the way you think it should. One comes to mind ...captured planes have special building built on a great tile but you can't upgrade/destroy the building.
Could be they designed it that way ... could be a bug.. Odds are this late stage its a design choice, but does look like a bug as well.
If its a bug they will fix it .. if its a design choice they may change it ... but certainly with the big companies after the first workable patch they move on. Atari dosent even host their own patch downloads, go figure.....
