Star Trek:
1. I won't die. Let's face it nerds, go into Forgotten Realms and you'll get gutted, go into a post-apocalyptic world and your ass wouldn't survive for more than half an hour.
2. I will lead a good life. If I go into the Star Wars universe I'll just be an average man, still fighting his way through life in order to get something good. Star Trek, you are basically living in an Utopia.
3, Great career opportunities. In most fictional universes if you aren't the chose one or gifted from birth your destined to be living an uninteresting boring life or die trying to be someone, you know, in short - be an NPC. Star Trek? Everyone has achieved something not because they were born special, but because they worked hard, gave it their all and saw their dreams come true.
EDIT: I don't think I'll need to take anything with me, hell, even my credit card would be useless.
