Hm...
Gyakuten Saiban Series (does it count? It's got a lot of VN-ish aspects, so... But I like it.)
Sakura Wars: So long, my love (Yeah, was quite nice, especially since I'm a Fujishima fan and also a New Yorker at heart)
Deardrops (Ah well, was quite nice, but didn't catch my attention that much)
Galaxy Angel (Reminded me of Sakura Taisen. Dropped it b/c I didn't like the combat system)
Overall, I'm not a big fan of the genre. Characters often tend to be too much the same and the stories are sometimes plain boring. (This is based on the VN animes I've seen this far). I might give the Disgaea VN, coming to PSN this month, a shot b/c I like Disgaea, but all in all, it's not my genre. If I want a game with a lot of story, I play a RPG or games like Heavy Rain or God of War.
