Depends what kind of characters you like to play, I suppose.
When you say it like that, it does make me think...
I played GGX, #Reload and AC+ but, as with practically every game before SG, I was conscious of the intermediate to advanced techniques but never made a real attempt to learn and implement them. I played the game mostly because I loved the art direction, was completely entranced by the music (I recall a IGN article that had 1m samples and me having those darn things looping on Winamp... the internet poverty days.) and it was great to have a real contender in the genre that wasn't from Capcom or SNKP.
While I played a LOT of characters, I'd say my mains were Faust and Venom (finished Survival with Venom!) in GGX, Zappa and Slayer in #Reload and Johnny and EX Baiken in AC+.
But really, your question did get me thinking about my experience with the series and I realized one of the things I enjoy the most in GG are the special moves. It sounds weird but I've always enjoyed the "ooomph" many of them packed. Examples would be Zato's command grab, Testament's Grave Digger, Johnny's Mist Finer and Ensenga (this move got me motivated to learn how to TK motions), Slayer's back step punch, Potemkin's anti-air grab, etc. It's also why I like EX characters so much. They have all sorts of new moves and EX Baiken's HCB+HS is probably my favorite special move in the game.
Back to I-no, as I admitted, I'm the one to blame for playing in a very superficial level. Even for all my CASULness, I won't bash a character's viability or "fun factor" because of my own ineptitude.
Boy, that stretched out a fair bit. (.__.)
Moving on...
All that's missing is her formal dress but I wouldn't be surprised if it's already colored. They're working really fast.
So, those last few frames in air throw some Sek actions and it's a wrap? I think it's fair to believe Eliza will be complete before the end of the month but release is another story. Dang consoles and their protocols... :/
