Tabletop roleplaying games are games where players collaboratively create a story — one person (the Dungeon Master, Game Master, or Storyteller, depending on the game) describes a world and its situations, and the other players describe what their characters do in response. The dice determine outcomes when success isn't certain. The result is something between improvisational theater, collaborative fiction, and a strategy game — and it's become one of the most popular hobbies in the country.
The Basic Structure
A tabletop RPG session works like this: the GM (Game Master) describes a scene. The players, speaking as their characters, decide what those characters do. The GM describes what happens as a result — sometimes based on the rules, sometimes on their judgment about what makes narrative sense. When a character tries something that might fail, they typically roll a die (usually a 20-sided die in Dungeons and Dragons) and add relevant modifiers, then compare the result to a difficulty number. High rolls succeed; low rolls fail or succeed with complications.
Sessions typically run 2-4 hours for casual groups, longer for dedicated campaign sessions. A "campaign" is an extended story told over multiple sessions — weeks, months, or years of weekly play. A "one-shot" is a self-contained session that tells a complete story in one sitting.
The Most Common Games
Dungeons and Dragons 5th Edition is the dominant game — the one most people mean when they say "D&D." It's a fantasy game with elves, dwarves, dragons, and dungeons. The rules are well-documented, the player base is enormous, and organized play (D&D Adventurers League) runs at game shops across the Midwest every week. If you're starting out, D&D 5e is the most sensible starting point simply because of the infrastructure around it.
Pathfinder 2e is the other major fantasy RPG, published by Paizo. It has a stronger rules foundation than D&D 5e for players who enjoy mechanical depth, and Pathfinder Society organized play is extensive across Midwest game shops. Many experienced D&D players migrate to Pathfinder for its greater tactical and character-build complexity.
Call of Cthulhu is the definitive horror RPG — players portray investigators in the 1920s encountering the Lovecraftian mythos of cosmic horror. The tone is dramatically different from fantasy RPGs: characters are fragile, sanity is a resource, and the outcome of encounters with monsters is rarely "you fight it and win." It has a loyal dedicated community in the Midwest.
Beyond these: Shadowrun (cyberpunk fantasy), Blades in the Dark (heist fiction), Fate Core (narrative-focused universal system), Ironsworn (solo or cooperative), and hundreds of independent games serve every taste and play style.
What the Dungeon Master Does
The Dungeon Master — also called GM, Game Master, or Storyteller depending on the game — is the person who runs the game. The GM prepares (or purchases) adventures, describes the world to the players, plays all the NPCs (non-player characters), adjudicates rules, and improvises when players do something unexpected. Being a GM requires significantly more preparation than being a player but is also the most creatively satisfying role in the hobby for many people.
Good GMs are not adversarial — they're not trying to "win" against the players. The goal is collective storytelling: the GM creates challenges and situations, the players create characters who engage with them, and together they tell a story neither could create alone.
