Still the gold standard for city simulation games even after 23 years. There is still not a game that feels so alive, so lived in, that matches all the intricacies established by this game. It's not perfect, but it's unmatched.
Community is still decently active and there's a plethora of amazing mods that elevate this game even more.

If you like 3D cities and free-form roads go for Cities Skylines. If you want to experience timeless-in-every-sense-of-the-word city simulation with believable population counts, go for this.

it's great guys, play it

Great game but crashes a lot.
