After the forward introducing the new magazine, the first article is by Fritz Leiber! He's writing about his own role-playing game, Lankhmar:

The next article describes how to run the Battle of the Five Armies using miniatures. It uses an existing "Battle of the Five Armies" rulebooks and a further modified version of Gygax's Chainmail rules. The rules are less interesting to me than seeing exactly what sort of scenarios early gamers were running through, and you can imagine how Battle of the Five Armies - a natural for fantasy wargaming - would lead to someone wanting to work out how to "run" other parts of the Hobbit.

The early issues of this series all have articles on another early RPG/scenario called Empire of the Petal Throne.

The first issue includes for the first time rules on how to use ability scores for random checks. The article is titled HOW TO USE NON-PRIME-REQUISITE CHARACTER ATTRIBUTES implying that prior to this you were just focused on which attributes mattered for combat.

Other game releated features include a debate on using magic & science together, the use of languages, running sessions in the wilderness instead of just dungeons, and the introduction of the land shark (bulette) using the same picture that winds up in the 1E Monster Manual.

There are also some low quality cartoons...

...and quite a lot of fiction, including the beginning of a novel called Gnome Cache, which will be continued in future issues (i'm not reading the stories).
