3DS Max (or Maya, same company though, and basically sister-projects at this point) has basically been used in one way or another for a ton of games and movies. Basically industry standard to use of them, and lots of knowledge can be transferred between the two.
Both 3DSMax and Maya eventually ended up being bought by the same company (Autodesk), but they have very long separate histories and entirely different roots (Maya is coming out of the highend Silicon Graphics world and was mostly used in the movie industry, while 3DSMax was the "PC underdog" at the end of the 90's but has always been very popular for PC game development).
Funnily enough, the "Games" marketing page for 3DS Max features WIP images of The Witcher 3 character rigging: https://www.autodesk.com/campaigns/autodesk-for-games
