The Binding of Isaac: Rebirth is going to be a pretty big game, there’s no doubt about that. One of the selling points of the original Isaac was that there were a lot of monsters, items and rooms to randomize, making each run feel unique, so it was only logical to vastly increase the amount of stuff for the remake. Edmund McMillen has now shared the exact numbers with us and they definitely don’t disappoint.
please note: when I mention the amounts for the original game, that includes the stuff that was added in the DLC
