I think it's safe to assume that a fair number of people still enjoy choose-your-own adventure stories. Otherwise there wouldn't be so many of them in book stores and gamebooks wouldn't be much of a thing on the App Store. But what if you want to make your own choose-your-own? Well, that's what Wunderverse is here for.
Wunderverse is an editing tool that allows you to construct - and even share - your own interactive adventures. There are several different template worlds you can use, with more to come. Once you pick a theme you can start dropping in events, endings, if/then conditions, and so on. It comes with its own "demo" adventure of sorts, but the real draw is being able to both make your own and see what other users have made.
If you'd like to try your hand at your own branching story you can find Wunderverse on the App Store now for $3.99.
