You think Minamimoto has the potential to be an interesting character from the issues that were hinted in Another Day?
Do you mean his issues as the "Tin Pin Professor" who was trying to live up to his master, Ken "Sebastian" Doi the ramen man, or did you mean to say New Day?
If it's the latter, then you should know that while I've played the DS version of this game to death, this is my first time playing Final Remix. Never played Solo Remix either, so any new content post-DS will be new to me.
Either way, I believe every character has the potential to be an interesting character; it all comes down to how you use them. And Sho's a character already consumed by ambition and devoid of co-operation, with a wild view of things. He's kind of like a quirkier version of Neku at the start of this game, in some ways.
So for sure! It's definitely possible and if he's going to be working with people in this new game, then he's getting thrust into unfamiliar territory, just like Neku was, which is always a good start towards development.
Might as well add that I've been avoiding the trailers for NEO after the first one, so aside from odd bits and pieces, I know very little about it. I like going into things as blind as possible.
