Critics about the achievements
While I really like achievements (yeah kill me), I am kinda disappointed how CiV represents them. I have no indicator if it belongs to a dlc or not.
Thats kinda stupid. You should have put this into the description.
I do not own any DLC yet, so I can just try one and if it does not work, it was just wasted time. Still, I like the Challenge, but it is really pointless if you do not know which DLC you need or if you need one at all.
Please make this better in any future title.
Doubtless they hope those undone achievements icons will drive some completionists/perfectionists to purchase the DLC because they can't stand having them unfinished there taunting them.
Anything under the "By the Waters of Babylon" is DLC. Khan related ones included, though everyone has that by default. So if you really need to know, just look under what I previously stated.
But I do agree that DLC achievements should have some separation so you know that they're DLC required.
