Popular games for collection Sister Princess

The premise behind Sister Princess is that an ordinary young man (the player) is made to live with twelve lovable little sisters, each with their own distinct quirks and personalities. Players have about a month to spend with the sisters with each day broken up into three segments: first is the free time period before noon, followed by the period after lunch and ending with another period of time before bed. During day time, the player can choose which of the girls he wishes to escort to school, if any. The period after lunch is similar to the one in the morning, with additional choices which allow the player to go to various places in town besides walking home with one of the girls. Every night before bed, the player will be allowed to check his e-mail and send replies. As the player continues to interact with the sisters, their reactions to their big brother will change accordingly until the ending. There are two different endings for each sister: the normal ending and the "non-blood relation" ending. As the name would suggest, the special ending reveals that the brother-character and sister are not actually related by blood. In the case of some of the older sisters, this can lead to the protagonist and "sister" marrying one another.

Sister Princess: Re Pure is an Adventure game, developed and published by Marvelous Entertainment, which was released in Japan in 2003.

The story begins on the final day of school before summer vacation. Then the player chooses a sister who he wants to start with for a close relationship. Therefore, Sister Princess 2 is about spending the player's time with either one sister or all sisters at the same time as they spend their summer together. Especially in Sister Princess 2, the player can spend the summer with all the sisters, not just one, in a special ending where the sisters invite their brother to a summer party where the brother and the sisters would swear to be together forever. Sister Princess 2 has four endings for each sister. The first two were the non-sibling relation and siblings-together ending and, if the player chooses one sister in the beginning but ends up with another sister, either of the other two endings for the first sister who the player does not choose appear ("non-blood relation" ending and "still brother and sister forever" ending also) but with a different story.
