One thing I love about Atlus is that they can't just simply port a game. They have to go all-out (All-Out Attack!) and add a whole bunch of new stuff to make sure that everyone is onboard. They break your power to resist buying a game a second time.
I was already onboard with Persona 4: Golden as it condenses one of my favorite games into portable form for the Vita, but they added so much new content that it's hard to keep track of all of it. This new trailer does a good job of laying out some of the additions, but there's so many that I've forgotten the first ones by the time the video ends.
New Personas, new story bits, new Social Links, new town exploration...and mopeds! Atlus should just set up something where they can have an automatic direct withdrawal from my bank account for new releases. Automatically take my money, Atlus!
