I played Assassin's Creed II first because I watched my friend play the first game and it looked like the most boring game ever.

I did play Hyperdimension Neptunia Victory first out of that series. And Shin Megami Tensei 2 first. Atelier Meruru was also my first PS3 Atelier game. Atelier Iris 2 was my first PS2 Atelier game.
