What if we did... Will of the Collective... set?
Only we could do a joke set along the lines of Magic's "unglued" (so who cares about balance, it's about silly fun & injokes - fitting for WotC) or (what I really want) a multiplayer set.
Why not? The game has rules for any number of players, so why not some stuff that encourages 3, 4, or 5+ players? (also, doesn't matter how much we break them since they were never planned on being tournament legal)
Stir Crazy that targets an opponent and lets them draw extra dilemmas and add them to the current mission.
Render Assistance that allows another player's ship or away team to join yours for a mission attempt (helping player gets maybe 15, 20 pts for helping if successful).
Consume dilemma that consumes dilemmas from another player's pile.
New battle card that doesn't stop you, but only one battle per player per turn.
I don't know, just seems like there's still plenty of space for WotC to play in, just not on the official roads, know what I'm sayin'?
