The Megara version comes with new art and new text - I know, because (see below) I never put "a" Cerberus in anything! So, even if you played the original book, it's obviously worth picking up the app for all the new material. I'm told there are over a hundred illustrations, all in full colour. All Megara's excellent work paid off and the app shot up into the charts in both the UK and USA. Oh, and you might like to know that, as an added bonus, Megara has relocated the action from FF's world of Alan to our own Fabled Lands universe!
