There are lots of good ones. >>143>>5594
But amnesia isn't one of the best. it's just well known because of the cage meme.
The love interests are cute but the fact that the MC is almost nonexistent in the games takes a lot from the game.
For one of the newer Japanese otomes, I recommend Psychedelica of the Ashen Hawk, it's localized. It has actual plot and a voiced MC with a personality, also plenty of scenes even for those you can't romance, more than most dating sims. If you pick the default names the MC will have a voiced name too.
If you want a western one, try Ebon Light.
If you like simulation/stat raising and having your character's name being called in a robotic voice, Tokimeki Girl's Side 3.
