I’ve used a lot of XP systems before.

Usually, you just collect points and that’s it.

City Builder on @Integra_layer works differently.

Here, I use my XP to join a city and build with other people. When I contribute XP, it helps the whole city move forward, not just my own account.

As the city grows, milestones unlock and everyone in the city benefits. It actually feels like working toward something shared.

Each city also has its own chat.
That makes it easier to plan, coordinate, and decide what to do next together. You’re not just farming and leaving, you come back, talk, and keep building.

If you have 10K XP, you can even start your own city and run it yourself. For me, this is XP being used in a more useful way.

Not just numbers on a screen, but progress you can see and take part in.
City Builder is live on Integra.
