we're having a game running and got into one of those discussions that are hard to clarify. I stole a unique agenda - and than the same unique agenda again. Is my first copy now burned? Can I score it twice? Can the corp still score it?
Or in other words: Does the "uniqueness" affect the scoring area? Are cards in there considered active?
It is not actually possible to score a unique agenda more than once.* There are 7 unique agendas currently in the cardpool** -- and all 7 of them say "Limit 1 per deck" on the card. IOW, if there's more than one copy of a unique agenda in the Corp's deck, it is an illegal deck.
* Technically, you can steal 15 Minutes multiple times since the Corp can take it back (which someone will almost assuredly point out if I don't mention it). But you cannot score or steal one while it's in a player's score area.
