I played this when it first came out for months non stop.

Part 2: Terror From The Deep was even better and I played that even longer!

Now Firaxis Games will be bringing us the original with remade graphics and gameplay.

I am totally hyped over the remake!

You can google for the xcom collecters edition for plenty of downloads for the originals.
I can also upload the first two parts if anyone is interested. (Yes I still play it xD)
