We did this game with DC quite awhile back...now it's time to do it with Marvel:
You're trapped on a desert island, and you can have only one of these 5 sets of comics. Which do you choose? Which do you choose?!?
You can pick a set because you haven't read most (or all) of the comics in it. You can pick a set because you have read them, and know you like them. You can pick a set based on future value--hey, what good does that do you on a desert island...but it's your choice!
