Pirates in Love. I don't know what I was expecting from such a terrible, cliché title but I decided to give it a go anyway. The writing was horrible, there were so many exclamation marks all over the place that it was like they'd got the author of Antigua to write a VN. I could barely get myself to the end of the common route, and when I found out they were actually charging per route I laughed and dropped the thing. I had a similar experience with Ninja Love, but I actually managed to get midway through a route before dropping it.
It disheartens me that most otome writers think that as long as they have hot bishonens they can throw any sense of plot to the wind.
I also dropped Hourglass of Summer pretty early on and just watched the OVAs, because it lagged like heck in both my computer and DVD player. The password system also got on my nerves.
