Mistearea

Besides Japanese, I'd have to go with only a few.  I've noticed that all of them have been mentioned already too.
Russian
German
Gaelic
The last two are because of ancestral reasons, but Russian is the odd one out because I simply enjoy the way it sounds.

There's the standard one. Yandere
And then there's this one.  It's a bit of a side-thing in that it's a bad ending.  More so since she's not really a heroine and just a support character.  But she does have a couple scenes.
Princess X

For me, the biggest reason is a combination of two.  I enjoy reading(which is why I read books as well), but the plot is always too linear to me.  I like them because it's a story that I can get into and also influence by the choices that I make at the prompts.  Often times when describing them to people I liken them to the old "Choose Your Own Adventure" books, which I used to read a lot during my childhood, because it's a similar concept.  Combine that with the stories that are being told and you have something that I find rather enjoyable.  That's why I'm not exactly a fan of kinetic VNs.  That's why visuals are lower on my list of priorities than with anime.

Margit got 1st?!  Excuse me while I go yell things that I can't remember if they are against the rules here or not.  I'm that happy.

Confession:  I used to have a sister complex so I have a habit to go for the imouto types in VN.
 
...Don't judge me...

Mine was taken from my favorite video game character's name, Mystearica Aura Fende(Tear Grants) from Tales of the Abyss.  Mystearica was too feminine, I'm a guy so..., so I changed it to Mistearea to sound a bit more masculine.

Well to be honest I don't read manga much but I may be able to assist you in finding it, try Happy Project.

Thanks again for the welcomes from the newer responders.
Favorite VN would have to be Grisain no Kajitsu.  It's really simple with the choices, seeing as how ever one of them makes a difference and there's not many, and the stories were all quite enjoyable to me.  Not to mention that it made me laugh so hard that it hurt.
And funny you should mention the Tales of series.  I actually own every PS3 Tales games.  Currently working on Xillia 2 and Zesteria.
And I'll keep that in mind with the reccomendations.  ...As soon as I get through my backlog, which consists of roughly 15 right now that I have yet to 100%.  ...One of them has so many endings that it just gets tedious though...

Howdy, y'all.  Mistearea here!  Just call me either Mist or Tear, I go by both.  Came here mostly because out of everyone I interact with, I'm the only one that really has an interest in VN.  ...Granted I did introduce a friend's fiance to the medium a few weeks ago, and she seemed rather interested.  Anyways, I'm currently a NEET that is slowly working on a novel while trying to find a job and new games I can try.  I can't exactly help with any projects going on, so the most I could ever do is be a supporting type.  ...Unless proofreading is still a viable option.
