I got really excited when I loaded up Steam and saw the title of the new expansion. It offers one new color to paint with, and that color is white. Snowfall, however, is even more narrow in scope.
I wasn't too upset because the core game is still a phenomenal foundation to build upon, and the expansion just gave us more to play with within that same phenomenal foundation. I described Cities: Skylines' first expansion, After Dark, as ' just tak the Cities: Skylines canvas, and offer the player a few more colors to optionally paint with.' That expansion didn't really do much to change the way that the game is really played, but rather just focused on adding further specialization options for any city that you care to build.
