It's a thriving time for interactive fiction right now. An explosion of new platforms and forms have arrived on the scene in the last few years. Varytale and inkle let writers create typographically gorgeous CYOA-style stories; StoryNexus makes more procedurally assembled, stats-based worlds that unfold slowly across weeks of play. Andrew Plotkin's Seltani is a web-based multiplayer ecosystem for easily creating living worlds, while Versu (co-created by Emily Short) is driven by complex AI for stories about character and social interactions. Existing platforms for interactive storytelling like ChoiceScript and Twine have become increasingly popular, rediscovered by new groups of makers and increasingly receiving recognition in the wider indie gaming world. 2012 XYZZY winner howling dogs by Porpentine was a 2013 IndieCade selection, while the prior year's festival featured Christine Love's Analogue: A Hate Story, a text-driven visual novel.
In short, it's a great time to be writing IF!
