A little over two weeks ago I wrote up my first impressions of Gemini 3 Pro Preview (https://blog.jcz.dev/gemini-plays-pokemon-first-impressions-of-gemini-3-pro-riftrunner) inside the Gemini Plays Pokemon harness. The very next day, I spun up a head to head race on stream: Gemini 3 Pro vs Gemini 2.5 Pro, both playing Pokemon Crystal inside the exact same setup.
