I'm really looking forward to Heart of St. Bathus because it's been authored by W.D.B. Kenower, who also wrote The Lost City of Barakus and The Vault of Larin Karr. Both of those are great sandboxes with ton of stuff to do. Bathus seems to be the same, but for higher levels and with plenty of Underdark stuff as well. At cursory glance, FGG did a horrible job with editing, layout, and visual direction, but I will endure.
HarnWorld 40th Anniversary Edition is a hardcover book with HarnWorld, Harndex, Lythia, Kethira, and 2 full color maps (Harn and Lythia).
As the product page says: “40th-anniversary limited edition deluxe HARDCOVER of the classic fantasy role-playing setting, rich with authentic medieval detail and bonus material. Over 300 pages of full color along with a 22” x 34” map of Hârn and a 22” x 17” map of the continent of Lythia.”
It really does look amazing. And is quite heavy too. Funny thing is that I forgot the book comes with maps, so that was a rather nice surprise!
Castle of the Mad Archmage Decennial Edition is a special Kickstarter edition which contains all core levels as well as all sublevels. I provided extensive feedback on all levels, and have been accordingly credited.
