Pipe dream anyone?

Eh, that SDK sounds like fun but, you said it best "pushing the boundaries" IS the fun part. Seeing what can be done within the limits of the system, or breaking those limits. That's the very reason you have to admire most all of the full hacks that completely change the game. Enjoy the hack or not, you have to respect what was done to achive the finished product.

This is still a dream though. Not practical in building or playing, but would be fun to see.

And while FF IV TAY was a so so game (yes I had a ton of issues with that game and every thing about it) it was great just to see the character's after years.
