After playing all these, I noticed something.
The most addictive online games don’t try too hard.
They don’t overwhelm you with tutorials or graphics.
They just drop you in… and give you small rewards quickly.
Then slightly bigger rewards.
Then suddenly you’re invested.
That loop? That’s the trap.
And yeah—it works.
