You are comparing apples and oranges. Old arcade games such as Asteroids offer challenges that Pinball does not. Some of the biggest games in modern day that are really challenging are more team based games such as "League of Legends". Pinball adds an element of physicality such as nudging and other various aspects. When Pinball players say arcade games require little to no skill I never understand it.

I wholly agree that games of today are getting more easier with every decade. There is that fine balance between difficulty and fun though. I got sucked into the Pinball hobby about 2 years ago because I discovered arcade's still exist, Pinball is more of a social game with people in real life, and just so many more things.

Off-topic here but VR will never take off in my opinion. They have made films, consoles, and even games on it and it hasn't paid off. They keep trying 3D as well and probably in the future, smell-o-vision as well.

Only time I see it taking off is at a arcade settings but seeing as that business is limited and how people abuse even Terminator: Salvation machines guns (hang them up please) I don't see it taking off.
