Here's some cover pic for Tsukihime and Fate/Stay Night
Tsukihime
Fate/Stay Night
Have played most of them. Ever 17 and most of Type Moon's stuff are really good.
Saya no Uta is well... not really my taste. Haven't tried Planetarian. And only watched the anime of Umineko, still waiting to buy some new hard disk before i can play it.
If you like Umineko you might also like Higurashi, it's made by the same author as Umineko
Higurashi no naku koro ni
oh yeah this is a Visual Novel that I recently played and it has quite a good story and a damn cool protagonist character
Sharin no Kuni - Himawari no Shoujo
