Context & limitations

The creator says they’re taking suggestions and adding features in real time. What would you add? The prompt below turns an idea into a playable feature pitch.

Do this yourself

Help me pitch the next feature for Grandma Theft Auto: https://grandmatheftauto.com/ . It is a free browser game set in London, starring a chaos-causing grandma. The current site describes mobility scooters, handbag-swinging, missions and side jobs. My favourite direction is ___ (a new mission, vehicle, item, landmark or multiplayer activity). First, inspect the live game and its Missions and Help screens if they are available. Separate features you actually observe from ideas in this brief or the Instagram caption. Don’t claim a feature is playable unless you can verify it. Give me three original feature pitches. For each, include a funny title, a one-sentence premise, the player’s goal, three gameplay beats, one London detail, a visual gag, and a simple way to keep it playable on both desktop and mobile. Keep it light-hearted and non-graphic. Avoid copying missions or characters from Grand Theft Auto or other existing games. Rank the pitches by player fun and implementation effort. Mark effort as low, medium or high and explain the estimate. Pick the strongest one and write a short comment I could leave suggesting it to the creator. Don’t claim the creator has accepted or built the idea.

A focused brief helps make the next feature funny, playable and consistent with the live game.
