Spoiler:
I played through the game as a Thief--seemed pretty broken considering Bleeding stacked some ridiculous amount. In the day two quests, I sided with Kyle both times because, seriously, who would ever side with Cartman. I ended up with mostly-100% completion. I think I'm missing 1-2 friends and some of the hidden achievements--it was hilarious when I beat Kenny--I didn't know there was an achievement for beating him in the makeover outfit, then I got it and was like #hype. They really thought of everything.
