lets see its out of something like Kingdom hearts, kicking ass with weapons that you would think have no real combat value, using magic, having to companions we travel in an epic space craft i make myself visiting worlds.
Or... pokemon, i know its pokemon but the idea of being able to travel the worlds catching creatures and using them for battle ...or stealing stuff.
finally ratchet & clank, its kinda like kingdom hearts only with incredibly over the top big guns that seem relatively easy to get with the mass amount of crates
