As an introduction to retro gaming this is an excellent place to begin. Of course the BECMI Rules Cyclopedia is a complete resource but the Moldvay is a great way to get started with the absolute basics of low level adventuring without having to wade through pages of information neither DM or players will need for at least 2 adventures. Currently introducing my children to the game with THE LOST CITY. Much fun and excitement.

The PDF's are good quality and I have printed and bound with spiral binding - a perfect old time resource.
