Below is a link to a Steam Punk themed MMO/Sandbox game that is coming out next year (end of 2017!) it looks extremely good and well thought out and detailed and the fact we can build our own empire / airships is an added bonus! it is advertised on "steam" at the moment so i've clicked on add to wishlist and following it to see progress of it, anyone else like the look of this game?.
