[Excited to showcase this cool THING you found]
Welcome to Doomsday Paradise!

[This is the narrative hook in a sentence- Janet/James is excited about it and wants it to sound fun!]
Play with your friends as heroes who’ve decided to put off saving the world so they can bum around instead.

[Janet/James is very casual about the whole apocalypse thing. They're very excited about stealing credit though!]
And maybe after you get tired of goofing around and showing off- deal with that whole apocalypse thing. Or better yet- steal the credit!
