How to use this prompt

Thumbnails need to read at 40px tall, so the layout must be simple. "Large blank rectangular title zone" reserves space for the real title in a design tool. "No real words" prevents GPT Image 2 from inventing a fake video title. The controller icon can be swapped for a sword, car, or any game genre symbol.

Variations to try

  • RPG version — swap controller for "sword and shield icon, dark purple and gold palette"
  • Racing version — use "racing wheel icon, red and black speed lines"
