I personally stand neutral on this discussion.
I have MK

and yes, I can admit it's not nearly as deep as soul calibur at all. It also has very cheap tactics if you know how to play right. Soul Calibur 3 on the other hand is a great looking game.
However I just do not have fun with Soul Calibur games. The game is a button mashers dream come true. You can push the same button combiations 3 times in a row, and it'll do 3 different moves each time. The game just is not that fun to me because anyone can just win and kick anyone's butt. The truly good people don't shine in this game IMO. You could close your eyes and just mash buttons and have a great chance of winning in SC3.
Still to this date, I just do not like fighters as much as I used to years ago. My most played fighter is SF2 on SF:AC on xbox live. I play that prety much once a week. Much more fun than playing these newer fighters IMO.
Until KI3 makes it on xbox360, I probably won't touch another fighter. SC has been dead since SC2 first came out in arcades IMO. Tekken hasn't been fun since tekken 3 IMO. VF hasn't been fun since VF2 IMO. DOA has always sucked. And MK hasn't been truly great since MK2.
Fighters just seem to be getting worse and worse, which is why I'm scared KI3 is going to ruin the franchise (because KI1 was so much better than KI2 IMO).
