expansion doing name copyright infrigement
An expansion to a game doing name copyright infringement https://store.steampowered.com/app/1059290/Talisman__The_Ancient_Beasts_Expansion/

The original game is trademarked as "Talisman", the update is trademarked as "The Ancient Beasts Expansion" which is a modification to Talisman. "Ancient Beast" is a trademark title to your game and not an update, therefore this copyright infringement is null and void.

So with that logic, I might as well make a game called "This is" and then release an expansion for it called "StarsCraft" 🐻
