Apocalypse (the third in the original X-Com series) had been a major improvement upon the first two games.
I'm not a big fan of restricting the gameplay to Mega-Primus, though.
Now, if someone made remakes of Enemy Unknown and Terror from the Deep using the engine and most gameplay principles of Apocalypse...
Least to say, that would be an ultimate embodiment of the X-Com concept.
I didn't play Cenega's UFO series, and I doubt I will (Starforce :not_ok
