Age of Exploration is a free fantasy RPG. The author writes:
Age of Exploration is an tabletop adventure RPG with fast character creation, streamlined mechanics, and modern rules. Character sheets are replaced by cards, and the quickstart rules are just 2 pages, making it a great gateway game to share role playing with friends and family.
Alterra is the base setting for Age of Exploration, a bright and flourishing world, where magic, technology, and culture are entering a global Renaissance. Unique races formerly separated across oceans and wild, uncharted continents are coming together to trade in exotic goods, arcane artifacts, and incredible new inventions.
Dungeoneer is a set of free wargames rules for an evening of dungeon bashing fun. The author writes:
These are a set of very simple dungeon-bashing rules for youngsters and the young at heart. This is classic kick-in-the-door, kill the monsters and steal their treasure stuff. One player is the Overfiend. He creates the layout of his dungeon, populates it with monsters and treasure and then runs the game. The other players, best between three and five, must guide their Dungeoneers through the dungeon hopefully to emerge victorious, alive and laden down with treasure at the end. Obviously it would be easy for the Overfiend to kill the Dungeoneers very quickly, just by placing a dragon behind every door. This is not his objective however. His job is to provide a fun evening that challenges the Dungeoneers, but may yet kill the occasional foolish or unlucky one.
Dungeoneer is about having a good laugh with your friends. If you play often then each player who wants to can have a turn as the Overfiend. This keeps things fresh and allows the regular Overfiend the chance to kick some monster ass.
