Pros: I bought this mainly for the Civ V Gold. I already owned Civ IV Complete and Xcom is an interesting game
Cons: It didn't come with Brave World which was known. Also didn't come with the randomnixed map scenarios. I really hate that there are so many "gold", "complete", and collections that don't actually have everything in them.
Summary: Playing X-Com was a treat, being a player and admirer of the original. The graphics are good, and play is pretty consistent, though there are a few quirks, that people have already addressed. The level of alien interaction takes an up-swing fairly quick, and some restrictions in the game almost seem to make it impossible to progress of succeed.
