I'm in the process of picking my favorites from the more than one hundred entries that the One Page Dungeon Contest received. It's a slow but steady task, as I want to make sure that everyone gets equal consideration for their work.
I won't comment on individual entries or let slip which have been my favorites of those I've read, but I will share two things that have occurred to me during the judging so far. One is that I believe I can determine with 95% accuracy what a contestant's preferred version of D&D is by whether or not they included a description of "Lighting" for their dungeon. This must be something that came into vogue with 3rd edition or later, because it was always assumed in the earlier editions that dungeons were dark - pitch black even - and therefore any need to specify the lighting conditions was unnecessary. This observation has no impact on how I score a particular entry, but it crops up so regularly that I thought it was worth commenting on.
Secondly (and I'm not finished reading all the entries yet so I may still be surprised), since the contest has ended and I can say this, is that if someone had entered a dungeon that featured six asthmatic kobolds guarding the Axe of the Dwarvish Lords (like the dungeons I used to write when I was ten did), I would have lobbied hard for that dungeon to be named "Most Totally Radical Dungeon Ever!!!"
In all seriousness though, you folks had some amazing ideas and everyone who took the chance to enter their dungeons, knowing they'd be viewed by complete strangers, should be proud. That takes some chutzpah.
