I thought a compendium of useful link sites might help players of the games, since these are no longer current. There are a lot of dead links out there. Getting to the goods is rather hard to do, nowadays.
I've found
this Might and Magic VI site extremely good for M&M VI, but frustrating. It has all the maps, dungeons, and points of interest everywhere, noted, but it loads as a single page. Don't try and print it.
Mandate Mania is an old M&M VI site, but very thorough. It also has maps that are well annotated, if not as thoroughly as the previous one. It also lists alchemy formulae, skill raising locations, and a suggested progression for quests. Good stuff.
