Fever_Discordia: This thread is for other games and expansions that are missing in the series of games that are already here on GOG, since no part of the X-Com series is on GOG then these aren't admissable for inclusion
(You can get them on Steam BTW, if you're DD site / DRM agnostic)
HellDunkel: Oh, sorry i thought X-com/ufo is the same series as the three Ufo games on GOG, only by an other developer.
And thanks, no Steam for me. I've got the original x-com cds by microprose somewhere on the shelves.
Oh yeah, the UFO games, definitely pretenders to the XCom throne but can not be said to be part of the same series
Smilar to another game that was heavily influenced by XCom, tried to go more real time-ish and ended up being a dull slog, which was 'Abomination'
Oh and you forgot the recent XCom remake / reboot that's suposed to be pretty damn good, off your list, of course!
