Whatever its faults, Cities XL cannot fail to be striking. Buildings are beautifully created with great attention to detail.
Even the art for the forums is no exception, with Focus hiring artists to create enormous pieces of digital art.
Focus have been kind enough to supply originals (tifs) which due to their size (one was >80MB) have been converted to JPG for inclusion on this page
