Why do microsoft tend to treat people like children?
This is degrading and frankly offensive.

I have never liked achievements in any form. It destroys the game's story and immersion.

Playing a game for me is like reading a book. I play the game for the story.

For a thought experiment: Would you continue reading a book if for every 10 pages you get an achievement?
"Bing! Nice job buddy! You have read another 10 pages. You are so hardcore, cool and awesome. You have earned 10 achievement points. Share it with your friends. Show them how cool you are."

What if microsoft implemented achievements in windows operating system? For every new feature you use and for every program and other actions you execute you get achievement points.
"Congratulations! You earned the suicide achievement for deleting the boot sector."


Get the picture?
If i could sue game companies for destroying the games, i would. They do not even provide an option to turn of that childish feature.

I know why achievements are popular in games. It is a psychology thing like how prices tend to be $5.95 instead of $6. Doesn't matter if a large population of people gets tricked by it. It still doesn't make it right.

Manipulation through psychology for greed should be illegal.
You should continue playing a game for the story, entertainment, enjoyment and fun of it. Not because of completion OCD that bugs you until you have gotten the full 100%.

Achievements is another form of a unhealthy drug addiction. You do not take drugs because you like them, you take them because you must. Because you can't live without them.

To take a quote from an activist: "Why do you and your company support an activity that is known to be mentally harmful?"

Causing harm even non-physical is illegal. Doesn't matter if it was intentional or not. That is the responsibility of the maker to figure out before release that the product is safe for use. At least that is how it is in my country.

For instance giving a drug to people that will cause addiction, mental anguish is illegal.
Achievements is exactly this. A drug that cause and promote addiction.
