The original Sword of the Stars games were deep and complex space strategy games akin to the Galactic Civilizations franchise. Sword of the Stars: The Pit takes place onboard a ship in space, but that is where the similarities to past games end. The Pit is a roguelike, giving the player control of a single character in hopes of surviving until the end against all odds.
The genre jump is a drastic change, likely in an attempt to appeal to a brand new audience. After all, roguelikes like The Binding of Isaac and FTL: Faster Than Light have taken the PC scene by storm recently. Although The Pit has all the great things that make roguelikes interesting, it doesn't make any real attempt to bring anything fresh or new to the genre.
