Epic Battle Fantasy 4 is around 90% finished!
I'm putting in all the battles and trying to balance stat growth just now.
From my testing so far, it looks like the game will be twice as long as EBF3, which means it should take the average player 20 hours to complete. And if that's too long, one can always switch to Easy mode at any time to speed things up.

20 hours? it took me days to complete EBF3
