Speaking of X-COM, I'll be getting Xenonauts as soon as there's a Steam sale on it:

It's basically a remake of X-COM that sticks much closer to the original. I'm looking forward to checking it out.
And although I haven't played the remake, count me as a third person who says the original is friggin' amazing. It's 20 years old, but doesn't show its age in any way except graphics-wise. It's still the best at what it does.
Anyone who has even a vague interest in strategy games and hasn't played X-COM, go on Steam and spend $5:

Guaranteed that you'll be astounded how advanced it is for a 20-year-old game.
Wow, hadn't even heard of Xenonauts. After watching the video that game is 100% on my list. Does look a lot like the original X-COM.
