I have to agree with Wizardawn on this one. The point of Labyrinth Lord, is precisely that it is a faithful clone of B/X, without bringing extraneous, modern elements into it. The AEC, in turn, faithfully clones the additional material from 1E AD&D, but in B/X format. The combined version we are voting on here is merely a collated, single-book version of those two existing products for those who run "Advanced Labyrinth Lord" as many here do.
There is nothing at all wrong with wanting the variety of options desired by grognard9 and others. BUT, in my eyes they are best suited to supplemental books, or are already found in other clones that aren't so strictly following an old rule set. If you are looking for a huge tome which includes all that stuff, I'd can't recommend any single book more strongly than Fantastic Heroes & Witchery. Free PDF or affordable in print, so you can't lose.
Lots of great OSR games to choose from out there, it's just that all those cool extras fall outside the scope of this particular proposed book.
