https://gwern.net/doc/ai/nn/transformer/gpt/dall-e/4o/2026-01-17-gwern-gpt52-fingerpointingatmoonsunset-vectorartstriped.jpg
Video game art is unique because it's interactive, requiring players to enact the plot and undergo transformation, making it difficult to describe or critique. Effective game criticism can only convey the transformative experience, which is subjective and cannot be scheduled or conveyed in words, making traditional reviews often unsatisfactory.
