Good point. I have all of it. How long did that take?
A long time, but not for reasons that you would think. After a few chapters, everything starts to blur together and you start missing little things.
Rough cut - 1 book per weekend. Then go over chapter by chapter - 1 per night. Things like the craft design took quite a bit longer - They were really messed up. Once I have finished a book, I set it aside for a month - when I review it, I find all of the mistakes that I missed while working on it - The iPad is great for reviewing things - spacing errors leap off the display.
I am not moving very fast, but I have far, far fewer errors & typos than the sewing circle managed with the T5 monolith.
I tend to rework things as needed - my group is about to start an exploratory mission in the Vargr Extents (My character is a 57th Century version of the conspiracy theorists you see on Ancient Aliens - and yes, he does have the bad hair.) So I have been re-typesetting and making corrections & updates to Mike Mikesh's Grand Explorations. 2 months ago it was working all of the DGP's Medical Digest articles into a coherent supplement for our party's doctor - don't have Advanced character generation done yet, but it is on my master list.
I have also done multiple versions.
Version 1 - 4th Edition MT - Errata Minus Rebellion Timeline information (Moved to the Rebellion Sourcebook) I needed the space to fit the corrections. I also haven't put the artwork back in, but I could do that over the course of a week.
Version 2 - Expanded - Errata + everything else I have found useful (Early Tech Supplement + 1 Small Step added to the Referee's Manual - Additional character classes & weapons added to the Players Manual - Imp Enc has all Library data replaced with the CT Library Data - many many articles added to the Referee's Companion). I have started on new artwork - luvs me some Poser 2014 & Vue.
When I start to update COACC this weekend, I'll also start on Nautical Force Command (The Wet Navy articles + the unpublished Sailor character generation system.) I built it once before a couple of years ago, but it definitely needs a new rewrite.
My goal is to have the entire thing done by Travellercon - I am running another adventure in the Verge sector & I need everything completed by then.
