You must bring all the parts and teach all the game(s).  You can only bring one box/bag.  You won't have Internet access.  And, umm, you have to carry the box up a huge spiral staircase.  What would you put in the box?

4 or 5 Martian coasters
3 or 4 additional sets of Martian Coasters. With that many pyramids you could get several games going simultaneously. This will keep large numbers of aliens occupied for a long time, thus allowing you to monopolise the snacks/make an escape.
