Versu is an interactive storytelling platform just released today by Linden Lab.
Basically, I see it as Chris Crawford's Storytron, except done right. It's a collaboration between IF author Emily Short and AI expert Richard Evans, combining written stories with sophisticated character and drama AI. So far it's basically interactive Jane Austen novels (seriously!), but it can support any genre of fiction, and more stories (and the tools for making them) are on the way.
You can read Emily Short's description of it and see some quotes from the Linden Lab CEO Rod Humble if you want to learn more.
I first came across this when it was demoed at GDC (before LittleTextPeople was acquired by Linden Lab) and I've been eagerly waiting for it to come out. Unfortunately, right now it's only available for iPad, and I don't have one. :( But it sounds like it will be coming out for other platforms eventually.
I recently started working at Linden Lab myself, and this project is a big reason why. Can you imagine something more revolutionary being done right now? :D
So, here we have interactive experiences fueled on storytelling, not gameplay. Sign me up.
Oh, and I almost forgot - Happy Valentine's Day! :) No new game from me this year, sorry (I went for something a bit more... personal). You could always just play The Love Letter again... ;)
