Spreadsheet-to-Sim Prototype Builder
Build a web app that helps creators model economy and trading simulations in a spreadsheet-like interface, then instantly play the loop through generated UI screens. The product reduces tool confusion and shortens the path from idea to testable prototype for data-heavy games.
Pourquoi c'est important
You want to make a trading or management game, but the core of your project is not animation or graphics. It is tables, formulas, market logic, events, and immediate feedback. The problem is that your current options are awkward: spreadsheets are fast but not playable, while full engines ask you to make architecture choices before you even know whether the loop is fun. You end up bouncing between tutorials, frameworks, and rough prototypes without confidence that you are building the right thing. A dedicated builder would let you define goods, ports, prices, routes, and events in one place, then test the gameplay immediately.
- · Conçu pour Indie game creators, hobbyists, and solo developers building menu-driven strategy, management, trading, or war simulation games without strong engine experience..
- · Monétisation la plus probable : SaaS subscription.

Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1Free spreadsheets may remain good enough for most hobbyists, making conversion to paid software difficult.
- 2The target niche may be enthusiastic but too small unless the product expands beyond game creators into broader simulation designers.
- 3If the generated prototype is too constrained, serious users may outgrow it before becoming long-term subscribers.
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
Several commenters independently pushed the creator toward spreadsheet-first thinking, data models, and immediate feedback loops rather than traditional engine-first development. The recurring theme was that these projects are fundamentally table and state driven. That repeated advice indicates a real workflow gap: users need a purpose-built bridge between raw spreadsheet logic and a testable game prototype.
