It was reported a few weeks ago that Cities: Skylines would finally receive a retail release on the Nintendo Switch. Just recently, the boxart for the European version of this physical edition of the game has popped up.
It’s not a particularly visually striking boxart, but it does match up with the other art for the game, at the very least.
As it currently stands, the jury is still out on whether or not Cities will also launch physically in North America for the Switch. At the very least, if you’re that interested in owning a physical copy then you can always try importing it, as the Switch is region-free.
