Today, the missus and I stopped at the LGS after work so she could look for some comic book issues she missed. While she did that, I dug through the used section and found many strange and wonderful things, including a lot of modules and material for Ars Magica, 3rd edition, which I just happened to pick up recently at the used book store.
Of the things I found, I ended up purchasing three AD&D 2nd edition modules: Wizard's Challenge, Wizard's Challenge II, and The Dancing Hut of Baba Yaga, for a total price of $7.
Now, I have owned both Wizard's Challenge modules before, and in fact I ran them in high school when the only available player was the party's mage. (He seldom missed a session, whereas the other two lads had summer jobs and were not always available on those boring summer days) I have no idea whatever became of my copies. I purchased them because I found them to be fairly decent examples of how to write material for a solo game, and in particular, an AD&D game with no characters who are skilled in direct combat. (A situation that my current group finds itself in, as the party is composed primarily of thieves and thief sub-classes) I recall enjoying running the modules quite a lot, even though I cannot remember all of the details precisely.
I will admit that, as written, these modules (the first one especially) do not fit well into my milieu, though they could be adapted. I doubt I will run them with my current group, because the only spellcaster among them is a bard. (My rewritten version, no less)
I bought The Dancing Hut of Baba Yaga because I think Baba Yaga makes just about anything cooler, and because the module is labeled as being intended for characters levels 7-20. I am mighty curious as to how a module can be written for such a diverse spread of power.
Plus, you know...it was three bucks.
I will, of course, have to adapt anything I use to AD&D1, but I honestly don't see that as being any real work at all. In fact, I think if I draw a pair of saggy mammary glands on the monsters and maybe draw a pentagram on the inside cover, it will pretty much be converted to first edition.
