I'll admit it, I thought the writing was on the wall for Xenonauts when XCOM:EU by Firaxis was announced and positive previews started to pop-up. But after playing the demo I am not convinced that EU is going satisfy old XCom grognards out there. It seems to be missing a good portion of what made XCom special, particularly soldier inventory and large squads. It also doesn't feel as nostalgic because it's so different (probably not important for new players but it means a lot to me)
I can say without a doubt that I will buy (wait, I already did!) and play Xenonauts because of these omissions and concessions.
