We really shouldn’t pick factions when we’re … tired.<br\>Smash Up: What Were We Thinking is an eclectic mix of factions that we couldn’t talk ourselves out of adding to the game. - AEG

Is that a Teddy Bear?

How motley are the creatures we find here!
O strange new box that has such factions in it!
What were we thinking? Tell, what’s in a name?
This set has factions standing for four ages.
At first the children, hugging Teddy Bears
Whose cuteness oft confounds opposing minions.
The youth will next pursue their favorite band
Of Rock Stars questing for the greatest bases.
Mature Explorers, restless in midlife,
Strive always to be first in new horizons.
Last, wise in life’s pursuits, the Grannies shall
Manipulate their decks to draw what’s needed.

This tenth expansion we now bring to you,
And celebrate achieving fifty factions!
