There's also Xblaze Code Embryo although I didn't like that one much.
, Monobeno -pure smile-, Time Travelers, Kaihou Shoujo SIN and Shin Hayarigami are all excellent reads.
There's White Album 2: Shiawase no Mukougawa, which is a personal recommendation, but that's only because Aquaplus/Leaf are the visual novel gods for me.
Then there's games like Dungeon Travelers 2: Ouritsu Toshokan to Mamono no Fuuin and To Heart2: Dungeon Travelers which are DRPGs with heavy visual novel storytelling. You could probably count on your hands the amount of localised visual novels there are, but it's increasing.
There's STEINS; Gate coming out on Vita soon which is an incredibly popular VN in Japan for its story (well-deserved I might add) so you should definitely keep that in mind.
There's obviously the classics like CLANNAD, Little Busters! , Robotics; Notes and Fate/Stay Night [Realta Nua] available on it as well, all excluding the latter of which are also on PS3.
