I haven't read that many VN's, but I'd include these two:
Soshite Ashita no Sekai Yori: Slice of life, very down to earth (notable is that fact that the protagonists parents are present as characters)
Midori no Umi: Mystery, Tragedy, Romance

To get your mind off it: you are now imagining a penguin on a hang glider...with booster rockets...who is flying along the antartic to their secret batman cave where everything cute and evil is busy plotting the demise of the world.
I finished Minami's route in http://vndb.org/v420 and now am playing http://www.youtube.com/watch?v=IbDwODNmPSU Haven't run into any choices yet, but I'm loving the mystery and atmosphere, even if I'm not expecting it to blow my mind..
