I've played them all except for whatever that Email thing is, going back to the original when it first came out on PC.

Just EU and EW.

the 3 first and the latest, but not the expansion. Oh and I played Enforcer too, but that is hardly an X-com game, if you count that in you should probably also add X-com: Interceptor.

Only Unknown and Within. I tried the first one, but I just couldn't really get into it.

I've technically loaded and played all of them but I never put enough time into the Email one and Enforcer to count those.

TFTD was actually my first XCom game. I've played that sucker for 100s of hours. It's brutal but interesting. Starting with that one made all of the others a piece of cake.

I've played all the "real" games in some capacity plus the disastrous train wreck that is The Bureau.

UFO Defense, Enemy Unknown and Enemy Within I played the hell out of.

Terror from the Deep and Enforcer I've loaded and putzed around with but not really played. Tried a little of Declassified (but not much).

Fart bucket, I thought I included that.

I guess that's the rule of poll creation: you will always accidentally forget one option >_<

I've beaten X-com, Terror from the Deep, Xcom, and Xcom Enemy Within. I got pretty far into Apocalypse but have never beaten it, also played Declassified it was a funish game. This is probably my favorite video game franchise. So hyped for Xcom 2!
