Pasión de las Pasiones

Pasión de las Pasiones is a PbtA tabletop role-playing game where you play the cast of the world’s most dramatic and exciting telenovela: Pasión de las Pasiones, as well as the family watching at home. In Pasión de las Pasiones, lies will be exposed, plots will be shattered, hearts will be broken, and if you’re lucky, you might even get a happy ending…at least for now.

An ashcan (demo) version of the game is currently available in physical format or as a pdf on DriveThruRPG.

RADCrawl is designed to capture the feeling and nostalgia of a Dungeons & Dragons that never existed through quick play that focuses on the dungeon crawling that makes traditional fantasy games great.

It also works to challenge existing tabletop assumptions by using elements of roguelikes, legacy games, and expandable card games.

Each character is created based on a playbook much like the playbooks of more standard Powered by the Apocalypse games. While some playbooks may be familiar, the design of RADCrawl is aimed towards picking out the weird and interesting pulls of the old D&D 3.5 days where character classes got almost absurdly specific. The Warrior is a totally legitimate class, as is The Kobold or The Gardener or The Romantic. These playbooks provide a randomly rolled selection of tiny-powers as well as some visual hints to get you off the ground running quickly.

In the fiction, RADCrawl is a popular sport enjoyed by a world of high fantasy through the use of vague and ultimately unimportant scrying spells. Players are the contestants in this sport, adventurers who delve into dangerous environments filled with traps, monsters, and wonderful riches. While the audience is (usually) not physically present, players will need to manage their reactions, sponsorships, and the arena judges.

The GM takes on the roll of this judge, a larger than life personality who provides commentary on the match and throws additional challenges or boons players way for giving in to their whims. This provides a feel beyond just dungeon diving, you're entertainers as much as you are adventurers!

During play, characters will get treasures through item cards. Unlike characters, these cards can be leveled up through play gaining new abilities and becoming stronger. Leveling up is not strictly linear, meaning one RADCrawl deck may have a Fire Axe That Slays Dragons while another has an Electric Axe That Improves Dance Moves. How your deck improves and changes will effect later runs, the Shortsword you improve in your first run will only be more useful on your tenth.

Whether you survive the Dungeon or not, you'll get opportunities to improve your Adventurer's Guild, gaining the ability to start the game with items, have additional supplies, or start with a favorable audience. Your items get stronger, you may unlock new playbooks or abilities, and you draw ever closer to being Heroes of the Arena.

From the ground up, RADCrawl is designed to be expandable. In addition to official expansions themed around themes, characters, properties, or concepts, it is easy for players or GMs to create their own dungeons and playbooks. The ability to create and sell new item cards will also be available to designers who wish to add to the Arena!

This means that you can play a game of RADCrawl at one table and have a radically different experience from someone else. Love bards? Get the Musical Interlude expansion and find instruments and musical spells galore. Want more temples? We've got you. Want something weird or off-genre? Heck yeah, we'll help you make it happen.

At this time, RADCrawl is in development. The full game is somewhere in the future, but a print-and-play version is available to my Patrons. It will continue to expand as playtesting happens with updates also available in my development vlog.

If you have questions or comments about RADCrawl, please feel free to get in touch with me! I'd love to hear them!
