I have been playing as Barry alot, he is certainly my favorite in the Reunion. His pistol is really awesome, it is actually the one that you can unlock in the REmake, if you finish the game in under 5 hours.
I really want to play Desperate Escape too, not to mention playing as Rebecca, altough I am really not to into her, she is probably my least favorite female character...she just isn't a very interesting character.
