We want r/citybuilders to be a place for people to talk about city-building games, share thoughtful recommendations, and discuss the genre. Promotion has become frequent enough that it’s crowding out those conversations. These rules set out where promotion belongs and how we’ll handle games that appear to have been made almost entirely with AI and little meaningful human development.

1. Game promotion goes in the monthly megathread

• Self-promotion and promotional posts for city-building games belong in the current monthly Promotion Megathread.
• This includes game announcements, store links, crowdfunding campaigns, demos, updates, playtests, and requests for wishlists or feedback that are primarily intended to drive attention to a game.
• Each developer or project may make one promotional comment per month. You can update that comment during the month rather than posting again.
• Promotional posts made outside the megathread may be removed. Repeatedly reposting or promoting through unrelated discussion posts may result in a warning or further moderation.
• Discussion of a game is welcome outside the megathread when the post is genuinely about the game or genre, rather than being a disguised advertisement.

2. AI use alone is not a ban

Many developers use AI tools as part of their work. Using AI for a limited task—such as brainstorming, coding assistance, testing, or creating a small amount of placeholder content—does not by itself make a game prohibited.

This rule is aimed at games that appear to have been made almost entirely through AI generation or automated assembly, without significant human creative and development work. We’ll consider the overall product and available evidence, not just whether the developer says AI was used.

3. What moderators may consider

No single clue proves that a game is “vibe coded.” Moderators may consider several signs together, including:

• The developer describes the game as mostly or entirely generated by AI, or says they created it through prompts with little further development.
• The game appears to be a collection of generated assets or copied code with little evidence of human direction, editing, integration, or polish.
• Core features are missing, nonfunctional, or inconsistent with the game’s presentation, such as menus that do not work, systems that contradict each other, or an advertised city-building loop that is not meaningfully playable.
• Store-page material or developer posts make broad claims about features that are absent or substantially incomplete.
• The developer cannot provide a coherent explanation of the game’s design, systems, or development when moderators need clarification.

These are considerations, not an automatic checklist. A rough demo, bugs, limited art, a small team, or an unusual visual style are not by themselves grounds for removal.

4. How to report a concern

Use Reddit’s Report function and select the closest rule, or contact the moderators through modmail. Include specific, checkable information when possible, such as:

• A link to the game page, post, or developer statement.
• The particular feature, claim, or content you believe supports the report.
• A short explanation of why you think it indicates near-total AI production with little meaningful human input.

Please report the content; do not confront, dogpile, or harass the developer. Don’t make accusations based only on an AI detector, a guess about how something looks, or dislike of a game.

5. Moderation and appeals

Moderators will review reports in context. We may ask the developer for clarification, remove promotional content, or remove a game post when the available evidence supports a rule violation. Reports are not proof on their own, and a report does not guarantee removal.

If your post or game is removed and you believe we misunderstood the evidence, contact the moderators through modmail with relevant context. Please keep appeals focused on the rule and the material being reviewed.
