We also gave a talk to a packed conference room about the gestation of Prison Architect - how we started out with Subversion, the things that went wrong on that project, and how a holiday to California resulted in a massive shift of projects. Eurogamer has published the video of this talk and you can see it here:

This is what the audience looked like from the stage

The Rezzed show generated quite a lot of articles on various websites. Here's a rundown of the coverage if you missed it:
How Alcatraz and a chatty taxi driver led to Subversion's death and Prison Architect's birth (Eurogamer)
The thorny issues of sexual assault and race in Prison Architect (Eurogamer)
The Eurogamer podcast on Rezzed (We are discussed around 18m)
I Am Indie: Chris Delay From Introversion Software (The Game Jar) (filmed on the show floor)
Prison Architect Preview from the Rezzed show floor (The Game Jar)
All of these article links went up on our Twitter feed first. We are basically using Twitter as our News feed now - more people follow us on Twitter than read the news blog these days. So if you haven't signed up yet, do so now so you get the latest.
