This document summarizes the creator's experience developing and selling the ZADE Action Framework Unity asset. Key points:
1) The asset was initially successful but maintenance costs outweighed income. Horizontal development and free upgrades prevented recurring revenue.
2) Issues like piracy, fraudulent purchases, and lack of support from the Unity Asset Store harmed the project.
3) In retrospect, the creator should have prioritized the main game, used cheaper purchased assets, focused on their strengths, and done proper marketing for any assets sold.
4) Going open source allows smaller updates and avoiding outdated Unity versions, since the creator now has limited time for the project.
