OpenGame

What is OpenGame?

OpenGame is an AI game generator and Studio workflow for creating playable HTML5 and 3D browser games. Its documentation frames the product around one loop: play a finished reference game, shape a written brief, generate inside a workspace called Studio, and keep the result as a portable browser-game artifact. The docs state that a polished chat message is not the finished product, and that the playable preview and exported artifact are the proof a run is complete.

OpenGame is presented as an independent product, and its pricing page includes a disclaimer that it is not affiliated with any third-party model provider. Support is listed at support@opengame.app.

How OpenGame works

The documented workflow has five steps. A user first plays a finished demo from the games showcase so controls, pacing, camera framing, feedback and restart behaviour are concrete before prompting. A homepage brief builder then turns a rough idea into focused requirements covering mechanic, genre and visual direction. The docs are explicit that this builder does not create a game and does not call the generation model — it only prepares a brief.

Generation happens in Studio, described as the workspace holding project history, generation progress, iterative changes, previews, downloads and publishing. Every 2D and 3D run consumes Studio Credits, with the fixed cost shown before submission. After a run, the site recommends testing the playable preview and changing one meaningful dimension at a time rather than rewriting everything.

Delivery actions sit next to the result: preview in an isolated player, download the generated HTML or a multi-file game bundle, or publish an eligible HTML game to a public OpenGame URL with a title, description, controls and SEO content. The site references quick HTML and multi-file output modes, including 3D ZIP export.

Main features

• 2D and 3D generation modes, selected before a run.
• A homepage game brief builder for pre-generation planning.
• Studio workspace with thread and run history for ongoing projects.
• Visible build activity and a playable preview.
• Prompt-based iteration tied to the saved artifact.
• Saved project files plus HTML and 3D ZIP export.
• Publishing to a public URL for eligible HTML games.
• Showcase titles that can be played and whose prompts can be inspected, including browser-playable 3D demos and independent builds made with additional custom work such as Blender and Three.js.

Pricing

All 2D and 3D generation uses Studio Credits. A 2D generation costs 5 credits and a 3D generation costs 10; the pricing page says the fixed cost appears before a run is confirmed, and that previewing and downloading saved work does not use extra credits.

Three monthly subscription tiers are listed:

• Starter — $15 per month, including 80 Studio Credits every month (16 2D games or 8 3D games).
• Creator, marked Recommended — $29 per month, including 180 Studio Credits every month (36 2D games or 18 3D games).
• Studio — $49 per month, including 360 Studio Credits every month (72 2D games or 36 3D games).

For all three monthly plans, credits expire at the end of the billing period. The pricing page also refers to one-time credit packs, which require no subscription and whose credits do not expire, and shows a Monthly/Annual toggle. The supplied pages do not list pack prices or annual rates, so those figures are not stated here. Unused credits are handled under the Refund Policy.

Common use cases

The showcase suggests several practical uses: prototyping arcade, platformer, puzzle, racing, strategy or physics ideas in 2D and 3D; studying a playable reference before writing a brief; remixing an existing showcase prompt as a starting point; iterating on controls and mechanics inside Studio; and exporting a portable artifact or publishing a public game page. Flagship builds, such as the wuxia case study and the racing and cinematic demos, illustrate how far a project can be pushed with additional hand-finished work.

Limitations

• Every 2D and 3D generation run requires paid Studio Credits; no free generation tier is described.
• Monthly plan credits expire at the end of the billing period.
• The homepage brief builder does not generate anything on its own.
• Publishing is limited to eligible HTML games.
• Pricing for one-time credit packs and annual billing is not disclosed on the supplied pages.
• A 3D generation costs twice as many credits as a 2D generation.
• Refunds are subject to a separate Refund Policy rather than being guaranteed.

Summary

OpenGame combines an AI game generator with a Studio workspace for brief, build, preview, export and publish. Its emphasis is that the artifact, not the conversation, is the deliverable. Pricing is credit-based — 5 credits for 2D, 10 for 3D — with monthly plans at $15, $29 and $49.
