Rails didn't make it.

But I think I missed the main point of the question. Should we add an addictive features to improve non addictive games? Will it be a plus?

Commercially, I think, it will. It's easier to sell, easier to spread the world.

From another point of view... It might change the game mood drastically.

Of course it's just my thoughts with no "that's the truth" thinking. I don't want to call games addictive because I like to play them.

Can addictive game be good? Yes.
Should the good game be addictive? No.
Should the game have a good core loop you want to play and return to? Yes with caveats.

In those games I do stuff to see a result. I do not necessary like the process but I'm still going because I'm hooked on that "you have the score" thing or when numbers go up.

From my point of view
Balatro is addictive. Vampire Survivors is. I like to play them because they toggle some lightbulb on my head. Or some idle clicker.

Okay. Then we should define an addictiveness.

Playing Skyrim and thinking "oh just one more quest" and "one more try" in Sifu. Are they addictive? I think not.

As often it depends on definition. Corpos might say - yes.

I think - no. If I would want to be addicted to the game it would mean I have some issues in real life.

You don't want to Party?

Damn... That's harsh...
Don't give up!

But what if the void will response...

Yeah. Just moving camera and hands using code and animation player in Godot.
