Just in case you didn't get enough Barrowmaze, +Greg Gillespie brings us Barrowmaze: The Forbidden Caverns of the Archaia.
Let me start this off by saying I backed this at $100 on the first day of the Kickstarter. Greg does some of the most accessible writing of Megadungeons that I've seen, and Barrowmaze Complete, while huge, is made to be broken down into easily digestible pieces (and if you don't already have BM Complete, you can add it for a mere 50 bucks)
More Barrowmaze is, quite simply, more better :)
Seriously, at a session a week you could probably game for years with Greg's releases, and why wouldn't you? It's a blast (I enjoyed running Barrowmaze with my regular group)
I can't wait for the summer to be over and the return of active gaming...
