The difference is stark. The Denuvo wrapper (removed in the P2P scene) was injecting checks every 250,000 simulation steps. v1.2.3f1 is the first patch where the game is .

This patch fixes the game. Your Steam copy is finally worth the $50 you spent. The "Mostly Negative" reviews should be re-evaluated to "Mixed." Conclusion: The State of the City Cities: Skylines II v1.2.3f1-P2P is a paradox. It represents the game we should have gotten at launch, stripped of its corporate leash and performance shackles.

With the arrival of , we have passed the first anniversary of the game’s tumultuous launch. We have moved past the apology letters, the performance roadmaps, and the “modder’s patch” era. This update represents something far more interesting: The Maturation of a Simulation.

Now, if you’ll excuse me, my sewage pipes are backing up because I forgot a water pump. Some things never change.
