Warmind is already a registered trademark of Bungie (since 2018; Warminds are supercomputers in their
Destiny franchise).
Risky Business is already the name of a board game. Zone of War is kind of similar to Activision's Warzone trademark and would be reusing the same of a small indie game that claimed it first (
https://www.igdb.com/games/zone-of-war).
Mine Wars and War Studio don't have any existing games or conflicting trademarks pop up in a cursory search.
