Set said:World's Largest Dungeon. Ugh. How much do I loathe adventures that have lists of PCs that the material can't handle. If it's big, it should be inclusive, yanno, instead of being 'World's Fattest Book you may not be able to use.'
I'm not sure what your beef with WLD is, but come on over to the WLD mega-thread and I'll see if the good folks there can address it.
We now return you to your regularly scheduled thread, already in progress.
I haven't played much D&D (or any fantasy at all) this year, but I have to say that I did purchase some really swell books - namely Ultimate Power and Agents of Freedom for MnM2e. Awesome, awesome books. I'm slightly less enamoured of Mastermind's Manual, though that's a matter of personal taste.
Heroes of Horror is a book I really wanted to like, but I think it failed as an overall product, with some positively brilliant bits inside. I'll chime in with the crowd on MMIV - flipped through it at the FLGS and backed slowly away.
