Hello Hunters, i started playing C.H. again after a few years, having tried it on Steam a long time ago but then abandoned. I would like to buy something but i see that there are separate purchasing sectors (Bundle-Pizza) : 1) Basic Edition, Artifact Bundle, Citadel Bundle, AI Bundle 2) Pizza I understand what Pizza is for, but what are other Bundle options ? do they offer different content, or does the $19.99 Basic one contain the others as well ? Thank you.
