I'm really liking the Bundleopolis artwork on gog's front page right now with the futuristic city and flying ships.

So I'm wondering, is that artwork from a particular game or just something gog artists worked up? If from a game, which one?

You can find the Bundleopolis HD wallpapers at Imgur. No idea if the artist got inspired by a game.
