How to Know the Size of a Game?

Hi Thomas, The maximum size that can be copied is entirely determined by Firebase (our data host). Typically, the hard limit is around 100MB-- For reference, our largest module (Tomb of Annihilation) is around 30MB. Unfortunately, we do not have a way currently to display how large your game is. Our recommendation at this time is that, if you are a Pro subscriber, that you make use of the Transmogrifier in order to transfer out assets (especially characters) into repository games. From here, you can make further use of the transmogrifier in order to transfer content as needed as opposed to maintaining a comprehensive catalog. In regards to how much space is available: There is currently no size limit on a game size. Sorry for the inconvenience!
