An awesome sequel would to be a firefly character and help track down Joel and Ellie. Eventually kill Joel, complete the surgery on Ellie, and save the world. While, of course on the way, fighting bandits, the military, and the Hunters. Maybe, meet the Hunter's leader, finally and kill him/her and retake Pittsburgh. Maybe even overthrow Boston. I just really loved the fireflies overall, and would like a new character to play as on their side for the next one if it happens.
