On the surface it might look simple, but that apparent simplicity is what makes it so addicting. The limited possibilities of what might happen allows the player, and forces the player as you get further into the game, to think many steps ahead. In that regard it's much like chess, where pieces only have one "move" each, but the game as a whole is strategically very deep. It's not as story-heavy as FTL, and I didn't find myself getting attached to my crews in the same way, but the gameplay aspect of it has much more going on than FTL ever did.
