For an expansion this is a good one.
For me, and my system which way surpasses the minimum required needs of the main game and this add-on, this game was mostly non-stop trouble in a huge and maddening way.
So for the few moments at a time that I wasn't wanting to throw my system against a wall, the game was just peachy and had a lot to offer.
I think they need to raise the minimum requirements by leaps and bounds, and they need to get someone to manage their support team, because I couldn't get any help.
When I tried removing the game from my system, it caused a full crash and I lost a lot of valuable information. Truly sad indeed and a learning lesson.
I will never again be playing a Civ game on a system that has information I actually need on it.
