Thanks for the look at The Fortress, j2g! Digging the Creator-esque, 4-in-1 feel, and I like how they represented the iron bars. I wonder how this compares with The Desert Outpost. Exetrius, you raise a good point about the enchantment table. I can't see anything resembling it here, but I could have missed something (I'm not sure what that yellow part is for). They might be saving it for The Village.
Hearing that there will be a Minecraft D2C set is unprecedented. Exciting for me, even if the price point will make it unlikely that I'll be able to buy it.
If the theme lasts another year, hopefully they'll make villagers available in a small set next.
Personally, I can't have enough skeletons. More Endermen would be great, though, and I'm glad that they're not exclusive to The Ender Dragon.
I do agree with you that a library would be a given, although they feature a crude one in 21124.
