Sounds nice, but like bunny said, it looks a lot like SAO, I guess having a more In depth concept would make it look different.

For example, the reason on why the player are stuck in the game is not because of the GM but because of a broken script wich cannot be reverted or else the whole game will be wiped out and so the player along with it.

To me floor and zones are pretty much the same. Why not just an open world of fight and tragedies.

Point is? Clear the game, make it home! Hopefully you will survive!

I'm in actualy :)
