Well, Soulcalibur 4 was a disappointment if you compare it to 3 or 2, but nonetheless it is a very enjoyable fighting game, with awesome graphics, an interesting character customization(many hate it, I love it) even if it was watered down a bit since 3 and a good amount of playable characters and weapons to equip. The gameplay is fast paced and fluid, combos are as always easy to learn, but hard to master and while a few characters play almost the same, most of them have a very different battle style. The story is very disappointing though, nothing to argue here, as one of the people who actually care for the stories in Beat 'em Ups, I was very disappointed with this ending. The voice acting and the soundtrack are good though, and if you like your games in Japanese, no worries it has dual audio.
All in all a good fighting game, with a lot of parts where it could have been handeled better, nevertheless it's funny to play it with friends and make your own characters, and if you like Siegfried, Nightmare and co. you will grab it either way. :P
