Ok, so I assume im going to be the first person to talk this down. FFVI is my favorite the best game of all time, so I feel every time I see a fan game I have to make sure it does the original justice. Right off the bat im going to praise this game for NOT BEING A CONTINUATION, thank you for that. However, in some of the videos I see characters like Celes and Cyan, I thought this was in the past? I'll just assume they are test videos.
The game itself looks solid. It looks like the feel of FFVI, but at the same time it IS FFVI, seeing as you replicated all the maps and most of the new characters are just color edits of the originals. The nice thing about most FFVI sequels I have seen is that all the char sets, or most of them, are brand new and not edits. The game looks smooth however so that seems a good aspect. If it is 1000 years in the past, though, why would you replicate the SAME maps? Its clear that in the past the land looked differant rather than the present maps. The war scorched the land and made parts of it devoid. If you wanted to make this an original fangame, you'd re-create SOME of them, but design new ones as well.
As far as the story goes, dude, its 2010. Go ahead and give basic points away. No well in hell am I playing this knowing nothing. If someone hasnt played FFVI and they read into it, that's their fault. You have nothing about the characters, plot or even descriptions of the vids/screens. Gotta give info on something!
Now, since this is a backstory game, im interested in how you are gonna do it/which characters you're gonna use. Alot was explained in FFVI so im interested in this. Every single FFVI fangame has dissapointed me, I hope this one doesnt. It is so far the nicest one Ive seen, the battle system in VX matches up well with the original. Good luck to you, as long as you dont decide to bring magic back in the present time ;D
