AuthorIAm David L. Craddock, author of "Rocket Jump," a book about the making of Quake and the origin of first-person shooters. AMA! EDIT 1: Thanks for all the great questions so far! I'll be around until 7pm ET to answer more. If you're curious about Rocket Jump, check out the links below.

EDIT 2: Thank you again for a fun session, Reddit. Feel free to take a look at the book using the links at the bottom of the post.

Hi, Reddit. My name is David L. Craddock, and I'm the author of the book Rocket Jump: Quake and the Golden Age of First-Person Shooters. AMA about Quake, id Software, and FPS games from the 1990s!

Here's proof that IAm who I say IAm.

Rocket Jump is a spiritual successor of sorts to Masters of Doom, David Kushner's excellent biography of id Software's team and early years, and a book that had a huge influence on my writing. I wrote Rocket Jump through a combination of research and firsthand interviews with Quake developers such as John Carmack, John Romero, Tim Willits, American McGee, Jennell Jaquays, Sandy Petersen, Graeme Devine, and many others. The book concentrates on the Quake franchise as well as other foundational FPS titles from the '90s including Half-Life, Duke Nukem 3D, Rise of the Triad, and Star Wars: Dark Forces.

I published Rocket Jump on in December 2017, and as of this morning it's available for pre-order on Unbound, a crowdfunding publisher and platform. Unbound will be publishing the book in hardcover and in digital formats, with an estimated release date of spring/summer 2019.

I learned a ton about id's internal processes and culture while writing Rocket Jump, so I thought I'd pop in to answer questions about what I learned researching id Software, my writing process, the book's contents, and chat about our favorite first-person shooters. I'll be around starting at 5pm ET / 2pm PT.

For years, my family have been torn apart by the repercussions of domestic violence. For the past few months, I've been struggling to accept the reality of our situation. It's 11 years on, and I often feel like a failure because I still feel no closure after everything that has happened.When I was at school, teachers that were aware of what was going on would tell me that one day I would end up writing a book or doing something positive with my own experience. As the years have progressed, this has become harder and harder to motivate myself towards. I have had numerous conversations with social work regarding my concerns, written a lot of letters and even started a petition at one point. Each time, I have been pushed back or made to feel like a crazy and traumatised child. I am an adult now, but after being silenced and ignored so many times, it has become harder and harder to fight back and I have questioned my own sanity over the years.

1,031,120 - is the number of domestic violence incidents reported in England and Wales during 2016. Just ONE year. I’m always uncomfortable sharing personal things, but when there’s a chance to make a difference and bring about change by telling a story I think that’s more important than my own fears. Some of you might remember a petition I created years ago, I must have only been about 14/15 at the time. My brother, sister and I were placed into the care of my grandmother after living in a home of domestic violence for several years. I started a petition because social work wanted to send my brother and sister back to live with my mother and her partner as they said they had no evidence the violence was still ongoing. The reason they had no evidence it was still ongoing is because my mum was under his control and would cover up what was really happening and I had hoped they would listen to my concerns and acknowledge the risk in sending my extremely young brother and sister back to live in this home. I was thrilled when my petition gained 1495 signatures and a lot of support from the public and messages from people opening up to me with similar experiences.

Sadly, social work ignored my petition and I was told that I could be in trouble with the police for my petition if I didn’t take it down and shortly afterwards social work went through with their decision to send them back to live with my mother and my violent step-dad. As a young teenager it took a lot of courage to speak out and I think having my concerns ignored by professionals for years and years has made me more fearful of speaking out as an adult and eventually I lost faith in social work’s ability to protect children.

Sadly, earlier on this year it was revealed that the violence has in fact continued on for years. However, my mum finally made the choice to leave my step-dad and charge him for everything he has done. The police have had the polar opposite approach of social work. Now there is a chance he may go to prison for the things he has done.I think it speaks volumes about the system that the police can hear about the horrible things this man has done and think there is a chance he could be locked up because he is a dangerous man whereas the social work department seen a suitable home for children.

Their decision to send them back allowed this violence to continue on in the presence of my younger brother and sister for years. It’s time the social work department stop playing happy families and putting their targets/budget before the well-being of the children they are supposed to protect.The whole system is a disgrace and it has taken a lot of courage to share this story but I hope if enough people speak out then it will bring about change and encourage people who have been in similar circumstances to speak out and get angry until it can’t be ignored. If you see/hear something that makes you worry about somebody’s wellbeing then don’t ignore it - report it to somebody.

Things can’t go on like this.I am hoping by starting this blog and sharing my own concerns and experiences over the years, I may not only raise awareness and help someone else but may find some closure through writing about it.

EDIT: Grabbing a cup of tea and then I'll work through all the questions and make sure I answer everything. I'm not feeling well so will be spending the night in bed with my laptop so keep the questions coming, I'll be here all night to get through them. :)

EDIT 2: I am so overwhelmed by this response, I was not expecting this kind of feedback and all of you have made my evening and made me feel even more confident that I'm doing the right thing by starting this website. Like I mentioned in a lot of my comments, I am very new to all this and still getting used to things but I hope you'll all keep up to date with my posts and remember, if there is anything you would like to share then you can get in touch. Also, if anybody has any tips for building up a regular readership, that would be great.

ScienceIamAn Astrobotany (space plants) Researcher AMA! I served as MPP’s Director of State Campaigns from 2015 - 2017, and helped lead successful ballot initiative campaigns in 2016 in Maine, Massachusetts, and Nevada. At the end of November 2017, I was named MPP’s Interim Executive Director.

Today, there are reports that Attorney General Jeff Sessions will rescind the Cole Memo, which provides protections for states with legal marijuana from the federal government. If the Cole memo is rescinded, that would enable federal law enforcement agents to raid licensed, regulated, and tax-paying businesses -- businesses that employ thousands of Americans and generate hundreds of millions of dollars in tax revenue for public services including substance abuse treatment programs and new school construction. Jeff Sessions is ignoring the will of the people and he must be stopped.

I am determined to fight this move, to legalize marijuana, and to remind Mr. Sessions that marijuana must be a states' rights issue. Ask me anything!
