I actually liked the one Activision made - Call to Power 1. When it came out it got slagged off big time because Activision basically gave Sid the thumbscrew - so they made CoP, and Sid made Civ3.
Actually Activision was party to the lawsuit between AH and Microprose since they were the ones actually making titles for AH. They had to get something out of it since Hasbro was only buying the other two. So they walked away from the out-of-court settlement between AH and MicroProse with the rights to make one Civ computer game of their own (I think it was just 1 so they must have paid something or otherwise worked out a deal to later do more).
I don't think I ever played Call to Power 2 or Alpha Centauri.
