Classic Modules Today: G1-2-3 Against the Giants (5e)


In 1981, TSR published the module named “Against the Giants” with the module code “G1-2-3”. It was written by Gary Gygax and illustrated by David C. Sutherland III, David A. Trampier, Jeff Dee, David S. La Force, Erol Otis, and Bill Willingham. It consisted of a 32 page booklet and two cover folders containing maps. The material was previously published in 1978 as three separate adventures; G1 Steading of the Hill Giant Chief, G2 The Glacial Rift of the Frost Giant Jarl, and G3 Hall of the Fire Giant King.

This conversion guide allows DMs to run the original module with 5th Edition rules and provides a reference sheet for encounters. It is intended for at least 6 characters of levels 10-12.

To use this conversion guide you will need a copy of "G1-2-3 Against the Giants", originally available in hard-copy and now for sale in Digital format at

This is pointless, don't waste your money. It doesn't include the module or anything of value, just lists of what you would find if you read the actual module, and a couple of suggestions like "make a map".

Does this conversion include updated pre-gen PCs?

I bought your guide and it doesn't look like much of a conversion. I still have to do all the work. Also how many players is this module for? I think I'm going to go try this other guide:

Hi, thanks for your criticism. The module is intended for at least 6 characters of levels 10-12. I'll add this note to the product description.

The format of Classic Modules Today is to provide a direct conversion to 5e rules which preserves the original module without rewrites or re-balancing the encounters to be level appropriate. This is done to preserve the original feel and play of the module, which was not made to be balanced. Older modules were as much tests of player ingenuity as character ability, and encounters that were beyond the characters' ability to assault directly were not uncommon. Against the Giants is no different in this regard.

If you want the encounters to be manageable for direct fights, all you need do is adjust the numbers of giants in each location to match the style of play you're looking for.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
