the video game market is too big and too stable now.

Yea there is no one "video game market".

Certain segments like say Playstation, Xbox, Steam, mobile games, indie games, etc might crash but the market as a whole is too big. At least if we're talking internal reasons.

What could crash all those segments if is the economy world wide crashes. Games are a luxury and those are the first to be cut from people's budgets. That looks like a real possibility thanks to Western governments and their green hysteria coupled with sanctions against their own energy supplies.
