The great thing about finishing a game like this is that there is still a good amount of replay value in The Last Guy. There are all the V.I.P.'s that need saving, trying to top my own score, and getting more of my friends to play so I can compare scores to and issue bragging rights.
But none of my friends have the game yet. And I'm bragging to myself.
Still, here's hoping that more levels will become available!
