The game:
I had played the game with a friend. To download price I have now slammed here.
Civ V does many things differently. Many die-hard fan of the series will demonize the simplifications, another will welcome them.
I think for my part Civ V really succeeded. I had long played no Civ and found very easy access.
With the upcoming addon yes to missing components are submitted.
I think for the price you can not do much wrong. It may not be the best game of the series for some, but it's deffinitiv a successful turn-based strategy game.
