They were showing all of the Amiibos. It was cool seeing them getting unpackaged on that one IGN vid. Makes me feel like a kid.
I'm haven't got attached to any fighting game and get familiar with their fighting system except Smash Bros. In Street Fighter, Tekken, and BlazBlue, I still smash buttons which helps beat the easier levels. When you are trying clear the harder levels, I get my butt whooped for not thinking smart. I like fighting games, but I'm never got attached to most of them. I did love BlazBlue for its charming story and cast. I remember it more than the other fighting games.
From what you said about the characters and story, chances are I would like Guilty Gear. I probably play in order like I did with BlazBlue. Just got to find a good deal on Amazon or Ebay. I was confused by BlazBlue's story, but I didn't read the wiki. It takes the fun out of it. I won't do that for Guilty Gear. I go with the flow and get lost. It's fun for me that way. Does Guilty Gear have special editions? For BlazBlue, I bought certain games like Continuum Shift Extend since it had more stuff than original edition.
