The inevitable culling of games

I just got home from Gen Con, and between review copies and my own poor impulse control, I’ve spontaneously added another 4x4 Kallax’s worth of games. Problem is, I don't have another 4x4 Kallax lying around, or even the space for one if I did. It's time for another cull, and lord knows I've done it enough to have the process down to an art.
