Welcome to the TTRPG-Hangout!

Welcome to the Tabletop RolePlaying Games Hangout where we focus on playing in homebrew worlds of our own making, especially sandboxes - worlds where players are free to do what they want while the world evolves around them. This style of play works well in most types of roleplaying games, and is especially common in OSR and NSR games.

Mostly for Solo play

Most of the articles above are suitable for Solo as well as Group play, but in this section we focus on things that make the most sense in Solo play.

Why Play Roleplaying Games Alone explores the point of SoloRPGs.

Oracles

Who answers questions you would normally ask the Game Master when you're playing without one?

Yes/No Oracle can be used to answer any yes/no question you would ask your GM in a group game, and the answer might be superseded by a random event.
Action/Theme Oracle is a useful tool for all sorts of things in solo play.
Reaction rolls allow you to randomize reactions from NPC within certain boundaries.
Quantity Oracle is for when you don't know how big something is, or how many of it there are, and so on.

Systems for assisting Solo play

Sometimes it helps to complement your game's rules with systems tailored for Solo play.

Evolving NPC Personality and Love System will allow your PCs to get to know NPCs over time, and perhaps even find love?
D12 Tension System helps you make your world a bit more dynamic, by adding mechanics for keeping track of "Tension" - the current danger level.
D12 Dungeon Crawl System employs the D12 Tension System to make dungeon crawling more dynamic.
