Roleplaying games are some of the most popular explorations of the video game medium on the shelves today. Among them, there's no shortage of sci-fi-focused titles that let players expand their horizons beyond the earthly and material, towards the great unknown of space. But space itself is so broad, it only makes sense there's a slew of sub-genres to the setting, from gritty hard-sci-fi dramas to the whimsical, adventurous tales of planetary romance.
