Interesting question. Very entertaining, and very good novel answers. Also, my avatar has ninja'd Twad's answer above.
The OP and some posters with innovative answers should try the Mumorpuguh Fallen Earth sometime. (I got bored with it inside of four weeks, but I always do that.) You start with a fire axe for the intro/training, then die in a cutscene, then I can't remember what you start with. Crafting is a large part of the game, so early weapons and armor tend to look like the offhand equipment that people might initially use during a Zombie Apocalypse ( http://www.zombiesurvivalwiki.com/page/Melee+Weapons ). FE melee weapons include axe handles, lawn mower blades, crude spear, hammers, shovel, and my personal favorite, the pickaxe. Its slow and heavy, but a pickaxe to the skull is usually an insta-kill. [Its also unrealistic that someone can't duck a pickaxe!]
Ignoring firearms, because my avatar will save me, were I transported to an RPG, I would run away screaming. Then I would realize that I'm pretty much doomed anyway, so I would pick up an axe. Then I'd get bored with the axe and try a sword. Then I'd get bored with the sword and...
If I were transported to a JRPG, I would pick up any weapon at hand, and then attack the first person that I could find who had either: 1) a sword larger than a pony, 2) mind-numbingly bizarre hair, 3) way too many belts, or any other combination of those that might lead me to believe that that person was the main character in the JPRG. By attacking the main character, I accomplish one of two things; either the main character dies, the game is over, and I can go home; or I perish in the attempt, which is almost as good as the other option since I won't be in a bloody JRPG anymore.
