4X space strategy games seem to be the specialty of the Iceberg lately. After the fantastic Endless Space, the Iceberg Stardrive now launching a game Zero Sum Games that could be a great success thanks to some good mechanical and spatial bears, but it ends up being too prejudice by some bad design choices and some haste in release.
Those who have never played a game like that are the ones who will suffer in the rush. The few game tutorials may not be incomplete, but they are quite static and boring. If I had to compare them would have to be with the Crusader Kings 2, which despite being a great game, suffering from the same problem. Featuring tutorials relatively elaborate but not spent long texts without any interactivity, which reduces its effectiveness to less than half.
