20 minutes of gameplay isn't much gameplay

The whole thing looks pretty boring. Nothing really happening, you sail around an empty sea most of the time, until you engage other ships where you lob cannonballs from cannons at them. There's no music or anything exciting, you just sail in quiet and miss with cannonballs. It has a real No Man's Sky feel to it, where you don't actually do anything most of the time. More or less a walking simulator on steroids.
