This new trailer from Cities: Skylines kicks off a series of three clips revealing the passion for the city-building games behind this entry in the genre. Word is: "In the video, Paradox Interactive's Jakob Munthe and Colossal Order’s Mariina Hallikainen and Karoliina Korppoo share their visions for the game and love for old school city builders, as well as their charming obsession with traffic." There's also currently a signup campaign on the Cities: Skylines website they are calling a "petition" which will earn all who sign an in-game Japanese Zen garden, listing a couple of additional reward tiers to follow: a koi pond and some cherry trees.
