My Netvibes feed (I will avenge you, Google Reader!) has about two hundred rpg blogs in it. I really enjoy reading and absorbing what everyone is doing and it makes me happy to see that our little hobby still has a solid core of die-hards that keep the spirit of our little hobby alive. The stuff these guys come up with boggles my mind.
Blue Boxer Rebellion is one of those sites, and here is a great map of a town that he is giving away for free.
For more map goodness, I also recommend Dyson's Dodecahedron.
I also found this there. Don't you hate it when someone has the same idea as you, but does it way better? Can't wait to see how this develops.
