regarding the universes up for debate, Pokemon is the best out of all of them, not only could i catch and train amazing creatures, but it's wholly peaceful overall in that universe, minus the punk factions that are made up of weaklings who want to rule the world or simply get rich taking the ez route, i could fight off those factions easily with my pokemon expertise.

meanwhile here's why the other ones are not as pleasant as one would think:

Mario - ok it could be cool to live among the mushroom ppl, but it'd be like every minute that they are going nuts cause their princess gets kidnapped, that would get old fast...

Megaman - MMU would be cool to live in IF you were a robot... otherwise as a human your life would be in jeopardy constantly from rampaging robots, not an ideal living situation ya know?

Final Fantasy - yeah ok owning a chocobo would be cool, though i'd be too chicken to ride one... but other than that, the FFU is constantly under threat of oblivion from dark forces, take FF7 for perfect example, the world almost got obliterated by a meteor the size of a planet... again not an ideal living situation...

GTA - holy mary, mother of god... WHY would you think this is a good universe?? crime rampant, chaos in the streets, cops are more crooked than helpful... unless you're a frickin' crime lord or gangbanger, this is no place to be... the only good thing is it seems it's ok to hire hookers... and you sure dont wanna be one in Liberty City...

Sonic - now this might be OK, if not for other threats than Eggman trying to throw everything into chaos, sure i'd love to hang with Sonic and his crew, but would it be good to live in that universe? cant say with 100% certainty that i would, it isnt really much different from our world anyways...
