As I mentioned, I had my own bias before I asked the question and I’m glad to see that the majority of people are of the same mind: Keep it Labyrinth Lord and leave out the AEC. That’s pretty much what I’ve been doing in my home game and I always meant to keep the published version as close to the basic rules as possible. I shall strive to continue in that vein and remain pure to my original intentions.
That being said, if I do happen to decide that Level Eight really, really, really needs a floating, multi-eyed, eyeball monster, I might cite the appropriate page number in the AEC rather than take up valuable page real-estate reinventing the wheel yet again. Such occurrences, if any, will be limited to the absolute minimum and only be done when I feel there is no better route to go than to use something form the AEC. But such measures will be of the last resort variety.
Thanks again, all. Looks like it’s time to put my mining helmet back on, pay off my kobold guides, and see what lays beyond the Vrilya check point on Level Five. I’ll send progress reports as they develop.
