As an avid bishoujo game player this trope page really needs to be cleaned up.
I'm going to go through and throw out any game I know is not a Dating Sim. Da Capo for example is a Visual Novel as are probably about 1/2 to 2/3s of the examples on the page. Since they're also listed on this page
http://tvtropes.org/pmwiki/pmwiki.php/Main/VisualNovel
There is absolutely no need for redundancy when it's wrong.
Visual Novels should go on the Visual Novel page to avoid confusing people about what a Dating Sim is especially when the explanation explicitly shows the difference between Dating Sims and other types of Renai games. I will only throw out examples I KNOW to be wrong. Other ones I'm unsure about will remain.
If anyone familiar with Dating Sims would like to help, that would be peachy.
