I didn't like Fate: Unlimited Code, While it had some interesting character designs, I found the gameplay to be amazingly stagnant.
Tekken, Street Fighter, Soul Caliber and Guilty Gear were all superior. Even the King of Fighters Anthology (despite lacking 2002) provided a more in depth play experience.
Fate: Unlimited Code reminded me of Evil Zone, but without all the aspects that made Evil Zone fun and quirky.
I am curious as to what you enjoyed about it, perhaps I am missing something that made Fate stand out. I was really looking forward to that game, and I was highly disappointed when I finally got my hands on it.
