I haven't played Civ 5 in about 8 months because IMO it's a pile of garbage compared to Civ 4. I'm playing it now because I'm super bored and it's telling me I can't end a turn without promoting my unit. Since when has this been a requirement of the game??? Before all the updates it wasn't like. You could save promotions until such time that you need them. It was like that in Civ4 and was even a suggested strategy. Remember the good ole days when Civ wasn't a nanny game? You could do whatever you wanted and recklessly end turns whenever you wanted even without giving orders to units!? Is there any explanation behind this?
