Story:

In Single again you play the role of Frank,  a widower and soon to be divorcee. The story begins with Frank moving back to the Loft he used to share with his first wife. A place he never wanted to go back to after her untimely death.  You lead Frank as he starts his life over again, soon he begins to find companionship and love in places he never expected to.

Gameplay:

You play the story through the eyes of Frank in a first person perspective.  If you have played a visual novel before you already know the deal. If not, basically you read for a bit and make choices every so often that affects the story in some way.  That's really about it.

That being said there are a two things that I think are different from most other visual novels.  First Single again has a much bigger emphasis on the characters and story, as a result there are fewer "choice" moments than in similar games.  But some of those choices will have major influences on how different parts of the story play out.  For example a choice made in the morning could completely change the story in the evening or even days later.
   

Second, there's no point system in the game, hidden or otherwise.   When I've played other similar games and come to a "choice" it always just devolves into going though each choice and seeing which one gives a point and that's the one I go with.  To me that doesn't really seem like a choice at all and negates any replayability the game may have.  I wanted to avoid that so I just didn't put a point system in.  Right or wrong the choices you make are yours.
