Sister Princess: Pure Stories

The gameplay involves reminiscing about past events in the "Valentine Story", with occasional player choices that branch the outcome. The "Christmas Story" acts as a single, longer story that starts with an email from one of the heroines, leading to different directions and outcomes. Players can also visit various locales on the town map, which advances time and allows for dialogue interactions with the heroines.

Mini-games include a memory game where players match pairs of portraits from the female characters, and a puzzle game that requires matching tiles with numbers to solve a 4x4 image puzzle. Bonus content includes fully unlocked BGM player, CG albums with over a dozen stills for each heroine, and Christmas messages from each of the heroines.

The game comes with a unique manual, a folded paper that contains a manual on one side and a full poster with artwork from the front cover on the other. Additionally, a sealed envelope containing six trading cards featuring Valentine Story artwork is included.
