If you can help it, you shouldn't. It promotes the games to a wider audience if they get views/likes/comments. Nintendo doesn't deserve that free marketing, and you engaging with it makes it more effective.

I watch maybe 5 minutes of any of those Nintendo game videos because after those 5 minutes it becomes incredibly stale and boring looking at the same bright colors and round shapes all the goddamn time.

Also the fact that almost all Nintendo games amount to what is essentially a fancy arcade game with not a lot of depth to them.
