The cover art is totally rad as well.
Even though it's "targeted" at old school RPG there's tons of stuff in here for anyone who is past the "This splatbook makes my character Uber!" phase. Interviews, guest articles, cartoons, art, maps, reviews, convention advice, campaign worlds, the freakin 5th level of Hell!
There are dozens of reviews that'll give you details on what's in it. This review is telling you just go get it! Discovery of what bit of utter coolness is on the next page is akin to the thrill of exploring one more hex into the Wilderlands.
Fight On! #4 which I ordered a few days ago is "only" a 122 pages and $10.00 printed. But, I'm sure is just as worthy of praise as #3.
