I can't find the source for this (probably because I remember reading it in a magazine), but I remember when the gaming press was hounding Square-Enix about a FFVII remake not too long after FFXII was released one of the answers that was given (I believe to EGM) was that if they did it at that moment, they would remake FFVII using the same battle system found in FFXII!
At the time I rolled my eyes because, to me, it was clearly Square telling the interviewer f*** off in a polite manner, but....what if they were serious?
I thought about making this in the FFVII forum, but I figure that more people that liked this game would have their eyes set on this forum, so I decided to ask the question here.
Do you think it would work?
If they did it, there would have to be many, many changes to practically every area in the game! I don't think it would sit well with fans since you can only control one character at a time, but I think if they pulled it off correctly it might be doable. At the end of the day I wouldn't want it to be in an official remake, but it is fun to think about.
