The Galaxy's Worst Player

Tristan "Trip" is a 25-year-old professional nobody with a gambling problem and 20 dollars to his name.  After a lucky night playing an online game, Trip gets an email from a suspicious person, which is definitely not a scam.  One click later, and poof. His house is gone, and he is on the other side of the universe. Where being from Earth is illegal.  The Universe treats Earth and other "Exiled" planets as entertainment. For people to watch and bet on. Now stuck in this new galaxy, Trip decides on his two goals: 1. Survive to see his family again. 2. Free Earth from whatever got it exiled to begin with. Doing this is going to be a task, though, because he happens to be the worst player in the galaxy.
