I've started to take to reformatting the module/adventure itself and making radical revisions where required.
I've been scanning and OCRing in the text. I then format this in MS Publisher to a format I prefer.
As I go, I make the changes directly to the module text, add stat blocks from e-tools and flesh out the location/NPC/creature/treasure as I think it appropriate to my campaign.
The end result is something which is no longer someone else's work - but very much "my" module. The process of scanning, revising, redrafting and revising the manuscript allows me to become intaimtely familiar with the way the adventure is put together. So, in terms of "how many times did you read it" - it's probably far closer to half a dozen times by the point I am through with it.
The nice aspect is that I am generally quite proud of the output by the time this process is over and I have created something unique I'm pleased to have and hold on to.
This takes a great deal of time, mind you. About 2 to 3 hours of work for every 1 hour of game time by the time I am done revising and supplementing the maps too. That in itself is not so bad though. These days I find it hard to game more than once a month - so all the extra preparation time is just "gaming by other means", really.
