CC is the worst theme they could choose IMO, for multitude of reasons. Any B/W title would be preferable to CC for me. WAY overated Theme (and game), for my 2 bobs worth. Not "family friendly" ("Shoot the Bad Guy"? etc.). Cost of game will rise way too much due to amount of work needing to be put into it.
Makes more sense for them to take on building next run of Aliens! Lol (that is economicaly a basket case for them to take on as well).
Whitewater would have to be one of their best options I think. Fantastic unlicenced theme!
