Dungeon Crawl Classics Mega Bundle is a bunch of their old adventures, many of them for D&D 3.5, 4.0, 5.0, so the description is a bit misleading (though I guess those adventures easily convert to DCC RPG). I do own much of this from other Humble Bundles.

I don't own any of the D&D 4.0 or 5.0 rules though I suppose you can get the SRDs. The only interesting items are the DCC RPG annuals and such. Eleven items retail is $75 for $25 bundle price is fairly nice. But I don't want a bunch of duplicate adventures and I have so many D&D-type adventures already. I'll pass.
