I've built a simple 3D browser monopoly game with ThreeJS and I've barely touched Frontier models. Why I built it? - Wanted to play something with my girlfriend in our free time - Wanted to immerse myself more in the 3D world - Never really owned a monopoly set so I decided to build a digital one - Wanna have a chill game to play with my friends on discord And honestly I could add more to that list. Now, what did I use to build this: - ThreeJS - Cursor - Grok 4.6 - Astra & Opus 5 (One prompt each) - Composer 2.5 (Most of the work) I like to think of the latest most expensive frontier models as giant bulldozers that get most of the heavy lifting done, but they leave so much rubble behind them that using them to clean it up is not cost-effective, rational or practical. That's why whatever I build, depending on it's complexity I'll run 1, max 2 prompts of the frontier models, and then get most of the polishing work done with a model that has excellent cost:quality ratio. Composer 2.5 is still that model, it's absolutely amazing in my workflow, and most people are sleeping on it. Everyone is getting obsessed with the latest model without worrying about optimization in the long-run. Test the game out: https://monopoly-3d-world.zlatkomarjanovic-zm.workers.dev/
