Before the article that Abominatrix posted was put up on RPGamer, there was another one similar to it as well, months ago. The people who would create Final Fantasy VII-2, or the ones who presented the idea, had stated the chance of it coming to pass wasn't the biggest. They didn't mention anything at all about the engine though. It was just the sheer idea of trying to create a game that would live up to Final Fantasy VII itself. And...Since the idea was stated, I really, really, really did, and do agree with that sense of caution. Simply put, I liked the way the game started, progressed, and ended. (Although, I don't like to think of it as ending, since I'd play it again and again.)
But on the other hand...A remake would be very nice.
*INCOMING FINAL FANTASY VII SPOILERS*
Granted, I would probably consider Final Fantasy VII's remake just that, a remake. I would most likely consider it a different game in many ways. But I WOULD like to see what Final Fantasy VII would truly be like, if its production wasn't cut short by Sony's impatience. And if it does actually hold true to the current Final Fantasy VII, I may just consider the remake to be its equal. This is totally opinion based though.
I'd like to see the Aeris resurrection quest though, the possible story holes in the game filled, multiple endings (I'm fairly sure it was planned to have multiple endings, such as if you had Yuffie or Vincent in the party.), and on and on. I want to see what Final Fantasy VII was intended to be, at least, what some of the story was intended to be like. I don't expect a drastic change and new game, but I'd like to see what Sakaguchi and the SquareSoft staff had envisioned for the completed project.
I'm not worried about things such as the Aeris revival quest though...Or what effect they would have on the game. That's exactly what they are, sidequests. And in that, it isn't required that you perform the revival, so therefore, I think, everyone can be happy. I'd personally play the game over and over, just to see all aspects of Final Fantasy VII. I'm pretty open-minded, so...If there's a game I like, I'll follow it to the end. That's my take, anyway.
