Die Inflationsmodellierung war ein Albtraum, bis wir den Wechselkurs korrigiert haben

We built a game with a virtual economy. Our inflation model failed. Simple price increases did not work.

We tried complex algorithms first. We used Apache Commons Math. We got NaN errors. The results lacked insight.

We changed our focus. We fixed the currency exchange. We used FIX Protocol. We used eventual consistency.

The change worked.

• Playtime rose 25%.
• Retention rose 30%.
• Response time dropped from 500ms to 300ms.
• Error rate dropped from 5% to 4%.

Apply these lessons to your work:

• Break big problems into small pieces.
• Get user feedback early.
• Fix the basics before you optimize.
