Soul Calibur IV
Went through 6 story modes (Taki, Mitsurugi, Amy, Ivy, Darth Vader and Xianghua). And Snow went through Seig and Rapheal's modes. Might go through more or level up more in V or play a different game.
Soul Calibur V
Still leveling up because there are items we want. We are level 38. You know how I said our exp bar wasn't moving....well it does. It just stays at a number for a certain amount of levels. Now we need a little over 1200 for every level.
