David L. Craddock is the author of more than a dozen books about video games, including Break Out, about the history of Apple II games, and Rocket Jump, about the history of first-person shooters. "I tend to write a lot about games made in the '80s, '90s, and early '00s," Craddock says in Episode 481 of the Geek's Guide to the Galaxy podcast. "I love to write about creative people who had big ideas but very, very tight restrictions, and I think that from that comes some of the most enduring products--most enduring experiences--ever made." One of Craddock's most recent books is Stay Awhile and Listen: Book II, about the making of Blizzard's classic action RPG Diablo II. Craddock says this volume was a much bigger undertaking than Stay Awhile and Listen: Book I, about the original Diablo. "There was just so much more to juggle in terms of timeline, in terms of game," he says.

There is a pressing need to automatically understand the state and progression of chronic neurological diseases such as dementia. The emergence of state-of-the-art sensing platforms offers unprecedented opportunities for indirect and automatic evaluation of disease state through the lens of behavioural monitoring. This paper specifically seeks to characterise behavioural signatures of mild cognitive impairment (MCI) and Alzheimer's disease (AD) in the \textit{early} stages of the disease. We introduce bespoke behavioural models and analyses of key symptoms and deploy these on a novel dataset of longitudinal sensor data from persons with MCI and AD. We present preliminary findings that show the relationship between levels of sleep quality and wandering can be subtly different between patients in the early stages of dementia and healthy cohabiting controls.
