I don't know Cities: Skylines but I imagine each city rendering engine has its own set of challenges and performance considerations. Generally my point is: graphics programming isn't always trivial, and it takes time/practice to debug and optimize a WebGL scene with millions of vertices. Comparing this WebGL side project to a full-blown city-scape game engine is apples and oranges.
