"still in the game"? how would anybody not be still in the game
I took the wording from similar cards in the game "We Didn't Playtest This At All", in which players can get eliminated (and usually for very silly reasons like forgetting to say "Ah! Zombies!" before playing a card while the Zombies card is out). It doesn't happen in Dominion (obviously), but that's why it's an RBCI, and not an SCI (serious card idea).
Side note: would you say "
an RBCI" because R is pronounced with a vowel sound at the beginning, or would you say "
a RBCI" because 'really' has a consonant sound at the beginning?
