Indie game studio
Last update: July 28, 2026
ATMAC Games is an indie game studio run by a solo developer, Andrew MacMillan.
Backstory
For twenty-some years, Andrew was working in the patent industry. But in summer of 2025 he decided, before time runs out, to switch things up and learn to make computer games. So he did what everyone on YouTube says you should not do: he quit his day job (i.e., retired from patent practice) to pursue the gamedev dream.
