Back in the day, kids would beat anyone at video games, searched for tips, figure things out, beat the game at 200% etc
Now we have tutorials like "press A to jump" ... "well done !"
<<achievement unlocked 200 points>>
"use d pad to move to the location"
<<achievement unlocked 500 points>>
We all know --> win --> reward feeling --> more sales
The result after years of pre-chewed informations in games : they can't figure sh** by themselves, they don't want to search for any tips in order to improve, so what they do now ? they hire people to act as a "tutorial" when the game don't provide them.
