I played a demo of a game on Playstation 3 a year or more ago. The demo was of a boss fight. The fight was very over the top, like Dragonball Z over the top. I ended up fighting some guy on the moon, and then he transformed into this giant thing that was even bigger than the moon and pounding me into the ground. One stage had the boss using a very large sword.
I don't remember much about it, but it just popped into my head and I can't remember the name of it.
