A repackaging of the first three comercial TSR modules, this made perfect sense in 1981, as modules started getting longer. The original G series had some 15 pages each with maps and stuff, while A2, coming out at the same time as this repackage, was getting to 40 pages in length which is the length of the whole G series put together. In terms of content it’s pretty much the same as the original down to the artwork. You can see my reviews of each of the G series modules in earlier posts.
