From publisher blurb:
The Spanish game "Aventuras en La Marca del Este" began from the mind of Pedro Gil as a homebrew campaign for some friends in Spain playing the world's most famous game as devised in Frank Mentzer’s (BECMI) Red Box with 9 starter classes and new rules on mounted combat, aerial combat, seafaring and ship battles. Now, many years later, it is one of the most popular role-playing games in Spain. By enlisting incredible artists that are now rising stars in the RPG industry such as A.J. Manzanedo, Jorge Carrero and Víctor Guerra, the "La Marca" team produced an incredibly captivating "retroclone" role-playing game that is an old school experience wrapped in old world flare. The game is published in Spain by Holocubierta Ediciones.
Supported by Kickstarter, this is the first ever English edition of the game, now called "Adventures in the East Mark". This Basic Rule Set has everything that you need to play a game with the deep traditions of the original fantasy roleplaying game and imbibe it with an authentic European flavor.
