Frontier Explorer combines the old school fun of a gazeteer with a more modern and analytical view of sci-fi games and their rules. This issue (Issue 3) features articles and advice specific to robots and A.I.s of various types and how they can fit into a campaign; along with ship designs, and much more. Frontier Explorer is well written and contains a lot of good source material and advice for any sci-fi fan and/or gamer. That it's available for FREE is pretty damned amazing. My personal test for any publication is this: Is the content quality such that I'd pay for a subscription to it? Answer: For Frontier Explorer, absolutely yes.
