I may be interested depending on the expected writing length (I prefer more detailed characters, and settings with a clear objective), and the expectation on the characters. For example are we all supposed to be like the main focus of the anime/light novel? Or are we allowed to play hero characters?

Will we retain our knowledge of the real world? 

What's the power scale limit for our characters? Low? Average? Momonga level of broken?

Are we going to be strict with the mana/stamina limits like it's an actual MMO?
