Fight On! is an old school gaming publication. It will be most useful to people playing OD&D, Basic D&D, or 1st Edition AD&D. By extension it is also useful to people playing Swords and Wizardry, Labarynth Lord, OSRIC and other "retro-clones". That is not to say that it will not be useful to players of newer editions or other games. It is the kind of publication that gets the gears spinning in your head no matter what kind of game you play.
The first issue is a slim 30 pages, but it is packed with gaming goodness. Inside you will find random description tables, a new character race, three dungeon descriptions, some magic items and other various articles full of gaming ideas including a primer on sandbox building. The dungeons are presented in very sparse detail, this gives you enough to work with but leaves plenty of room to make it your own.
Overall I enjoyed the first issue of Fight On! and trust me they only get better, more on that later.
