hmm. so many good and exiting ones, but i want more of one without daily threats of death. and that narrows it down. soooooooo, pokemon. my rattata will show all of you! hehe

Honestly I would go with Guildwars 2. I might update this later when I go back and say, am I stupid or am I stupid this world is obviously so much superior, but off of the top of my head I'd have to say being a hero in that world would be the most entertaining.
EDIT: Without the existence of this community, I might be more of a DarkSouls kindof guy, but that's pretty far fetched and I think I would still pick Guildwars 2 over it.
