[FREE] Galactic Civilizations Ultimate Edition

Well... let's call it "crafty workaround" - winners will get what's been advertised, so that's technically fine according to the rules.
It's up to giveaway creators if they deem it morally acceptable or not, as they'd get a bit more CV than usual by exploiting a free key that, doing it that way, wouldn't be counted as free.
This is possible with any package that doesn't include DLCs, as the API will report games as owned, but can't check if games were obtained separately or together. Conversely, doing it with packages that include DLCs would be a misleading giveaway, as winners wouldn't get them.
