Life got...kinda weird after the portal opened. Don't get me wrong, a lot of stuff is pretty cool - the dinos in Central Park, the Re-Renaissance (when all those artists found out that the statues had been made modest they freaked), the restoration of Greek philosophy, all those things are cool.
But you've also got stuff like Ghengis Khan trying to conquer China again, only now with ground-to-air missiles, Napolean is running around France trying to establish a dictatorship, and the Founding Fathers are lamenting the fall of their idealized society.
And this guy. This guy think's his bike is a horse and he's choking up traffic. I just wanted to get to work.
