Sister Princess

The "Christmas Story" acts as a single slightly longer story which starts by the player reading an e-mail from one of the heroines which decides the direction in which the story continues.

Additionally, the game includes a town map which lets you visit various locales which advances the time.

The map also shows which heroines is at which location which will prompt for a dialogue if you visit a location with someone present.

Both visual novels require the player to enter the protagonist's name by which one is addressed to in the stories.

Mini-games include a memory game where you can play card-memory game against each of the heroines, matching pairs of portraits from the female characters.

A puzzle game is a single-player 4 by 4 tile matching witch one missing tile starting with the image you need to put together, then shuffling the tiles randomly.

Beside the picture, the tiles also feature numbers on them which help you decide which tiles goes where.

Additional bonus content include fully unlocked BGM player, CG albums with over dozen of stills for each of the 12 heroines, and Christmas message to player from each of the heroines.

The jewel case manual is a folded 3x4 paper which is a manual on one side, and a full poster with the same artwork as the front cover on the other.

In addition, the game comes with a sealed envelope containing six trading cards featuring the valentine story artwork of two heroines on each of the cards.

Sister Princess for PlayStation is currently worth €15.29 loose, €5.50 complete in box, and €14.00 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Sister Princess has only a handful of tracked market sales, suggesting relative scarcity compared to more common PlayStation titles.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Sister Princess, loose is €15.29 and CIB is €5.50 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
