Like many others here no doubt, I'll be buying the new X-COM 2012.
But will still keep on playing UFO:AI
Both games gonna end up having a different feel to them where the remake will feature a short and sweet affair even for the single player campaign. Anyone who's played the console version of Civilisation will understand my suspicion. I'm looking forward to the Firaxis reincarnation nonetheless, mainly for the flash and bangs but UFO:AI is still about the original experience for me.
I hope this project continues.
I hope UFO:AI evolve a little away from the original X-COM out of necessity to differentiate itself from XCOM: Enemy Unknown 2012.
A deeper geoscape strategy element eventually would be my suggestion coz that's what the PC is good for.
