I think bringing back projects on AGN sometime soon is very possible. AFAIK everyone's down for this, but I don't know anything more than that.
A google search didn't bring up much in RPGVX FF games other than IV (which actually looks pretty cool), would these be from japanese web sites?
(Side note; I'm sorta sad that rpg maker gets so much attention for clones of other games. ...I guess there's a reason why indie/fan rpg game engines are mostly non-existent...hmm.)
[EDIT] Added a poll with options that sound good to me. If you guys could vote for one that would be awesome, or you have something better then post it. :)
-Right now I'm leaning toward FF: Catastrophe, as that is what I call the 2D OpenGL Engine that it will be built off of (also hints at FF6 too) so it seems to fit pretty good.
