Games made by these channels or themed after them?
Lots of civil engineering or construction channels as city builders. Adam Something's would be an interesting one.
Boston Dynamics as a Kerbal-esque robotics game.
Dillongoo as a flashy, well animated action game.
Dropout as some fun party games.
Kurzgesagt would make for great, stylish educational games.
LockPickingLawyer as a sort of half skill half puzzle game.
Modern History as a medieval simulator.
Any tabletop/adventure channel as whatever sort of RPG fits best.
TierZoo as, well, the Earth MMO it already pretends to be.
