Tales of a GM is a blog that's always filled with neat tidbits, amusing anecdotes and helpful advice for a variety of games, both general and specific. I missed a few of these articles so I'm especially happy to have gotten this.
I continue to be a big fan of the Storm and Shield series. The series is a good reference source for adventures of all kinds and Galatic Gadgets is no exception to this. I highly recommend checking out the entire set.
