There is plenty to keep you busy for a long time in Soul Calibur V. You can fight other players from around the world and climb the leaderboard ranks. You can upload a video of your fights or download and replay others'. You can earn titles by defeating characters in Quick Play. There are some characters to unlock, either by completing Story Mode or fighting them in Legendary Mode. You will eventually find Assassin's Creed Ezio Auditore, Edge Master, Elysium, Kilik, Algol, Tekken's Devil Jin and others available in character selection.
Fangirl or not, I have to admit that I am disappointed by little changes that brought so much into the game.
