Imagine you're about to ship out for... anywhere. It might be modern-day New York or a far-future space station, a high-fantasy village or a wild west town, a post-apocalyptic zombie-scape or a film noire speakeasy. You get to bring one bag with you. It's a bag of holding, admittedly, so you've got plenty of space. In this bag, you must bring everything you could possibly need for a trip of indeterminate duration, in which you could travel to any number of universes. Your task could be nearly anything: surveillance, scouting, assault, or simple survival. The upside is you can select your equipment from any of these universes and have as many redundancies as you need. (Remember: In some universes, magic won't work. In others, no amount of technobabble can get your blaster pistol to function.)
So the question is, what do you take? I've got my list below, but I'd love input. Consider it a thought experiment that, as a side-effect, might help my URDR character live just a little bit longer.
