Yukigatari Renewal
Premise via IGDB
The game takes place in a snowy mountain area, where the protagonist takes part in a skiing course. Of course he isn't alone and, conveniently-enough, ends up with a lot of female company.
The protagonist's little sister appears as a new character.
Scenarios have been remade since the Dreamcast release, and new event CGs and endings added.
This version also adds voices for the male characters which original only female characters were.
