The best and safest way to play is to purchase the game from an official store like Steam or the Epic Games Store. You'll get a clean, virus-free version that can be easily updated, and you'll have access to the Steam Workshop for all those amazing mods that can fix performance issues and add endless replayability. Play it safe, and get back to building your dream metropolis.
