It's Old Father Time here—big beard, robes, clock fetish—spreading the harrowing news that Cities: Skylines is already a whole decade old. 2015 was, it turns out, actually quite a while ago, and not just the other day. Awful stuff.
Naturally, Paradox and Colossal Order are not letting this milestone pass without notice. A celebration is kicking off, across both games, featuring updates, freebies, free trials and new releases. Lovely stuff.
