I think my favorite part in SR2 was "Insurance Fraud". Watching your character pinball around, getting hit by trucks, and then "unfold" himself and do it all over again... That, and deciding your entire gang got to walk around the city dressed like ninjas. ("Wassup, my ninjas...?")
The whole thing looks like a lot of fun; I'm looking forward to meeting new characters, trying out the new videogames, designing my alter ego, and seeing how the plot turns out (I'm sure I'm going to enjoy smacking around what looks like a truly unlikable set of villains)... SR3 may be my most anticipated game for this year. (Sorry, Skyrim.)
