If gamebooks have a future, works like Metahuman Inc and 80 Days point to that future being in digital format. With all the advantages you can see why. It's easier to give readers a free sample. The device keeps track of any stats and variables so you can stay immersed in the story. The text can adapt to the choices you make in a way that a print gamebook, contrained by the physical limit on the number of paragraphs, cannot do.
This week we got wind of a new digital gamebook called Eternal Escape that's being funded on Indiegogo. You can read more about it here and play the demo here.
Evgeny Nesterov and his development team promise a 2000+ section adventure with a strong story hook. You wake up in a dank cell. Your memory has gone; you don't know who you are or how you got here. There's a 400-year-old statue with your face. And among the characters wh might help, hinder or eat you is a seven-foot ant called Tal. Who are you going to trust? It sounds like "Alice Cooper in Wonderland"! The campaign runs just one month, so jump over there and see for yourself.
