Oneshot... Not Campaign

In this episode of Inside the GM Studio, Matt and David dig into a practical question from a new GM who wants to write a one-shot that helps a group test chemistry without accidentally ballooning into an entire homebrew campaign. The conversation quickly turns into a useful guide for anyone planning a short RPG session: decide whether you’re building a true standalone one-shot or a prelude to something bigger, then work backward from the ending you want. They break down how to keep scope under control by limiting the number of scenes, narrowing the setting, and focusing on a strong hook, clear stakes, and a satisfying payoff. Matt makes the case for pre-gens and simple, flexible prep for new players, while David emphasizes tone, catharsis, and ending on a cliffhanger or mystery if the session is meant to launch a campaign. Along the way, they offer concrete advice on scene budgeting, roleplay balance, combat pacing, and how much worldbuilding is really necessary. If you’re a new GM trying to design a one-shot that’s both manageable and memorable, this episode is packed with smart, gameable advice without overcomplicating the process.
