B/X Essentials has been re-dubbed Old School Essentials. Which was funded successfully thru kickstarter. From what I gather there were a few changes within the rules and a name change. You can read the author's notes here. (Actually it's a very interesting and good read if you have the time).
What has remained is the original B/X Essentials in RTF format. And here's the part where I get into why its saving my ass.
First off, I've got a pile of clones and copies of D&D. Far too many. My current flavour is Charlie's Whitebox which I quite love. (I'm DMing it in a Isle of Dread Campaign at home). That being said I'm playing in a game with Tim and he's using B/X (specifically the Old School Essentials version I believe). Reading thru the rtf's and the author's notes, I'm falling in love with this game!
Having recently got my office all setup in the basement I moved down a few D&D books to have handy when playing. More often than not while playing old school games there is not a lot of need to pick up a rule book, but on occasion (like leveling) its handy to have a round.
I found out last night that the water pipe leading outside for the hose leaks behind the wall. After weeks of running a de humifider in the basement, the room was fairly dry. I felt like I could leave a few prized possessions on my desk for handy reference. After my wife watered the garden I went downstairs to move the laundry load over and realized the floor was wet. ACHK! Cue mild panic. Bring up B/X Reprint and put back on shelf. Then start dloading all the RTFs.
What I'll probably do is create a basic document within google drive for handy reference. Mostly just the core rules (equipment, classes and that's it basically). Just for a quick reference. I've switched over from using a paper character sheet to a google drive doc. As well all my notes are on the drive.
If you'd like to see them they are here and here.
Anyways, I gotta say thank you very much Necrotic Gnome for saving my ass!
