One idea I keep coming back to with Pixels is this:
good incentives are not just about creating activity.
They are about creating alignment.
That difference matters.
A game can have many users doing many things, but if those actions do not strengthen the ecosystem, the activity can become empty.
What makes Stacked interesting is the attempt to connect rewards with behavior that actually matters:
retention, loyalty, real participation, and long-term value.
That is why I think this story is bigger than rewards alone.
It is about building a system where players, games, and the ecosystem can move in the same direction.
