1. Machi de Uwasa no Hakushaku-sama: this game has great art. The comedy value is so high that I completely cracked up in the comedy routes. The heroine basically trolls the vampire male lead numerous times. xD It’s a short game so you could finish it in no time. =) There’s no English translation though. (Chinese translation, on the other hand, is available.)
Following games have English translations (that’s why I’m recommending them over others. ;-; They’re also fairly popular, so I assume that they appeal to most otome newbies. These are definitely not my personal top games though.
2. Amnesia: This was quite interesting, and it has got great art. Surprisingly, I really liked all of the characters, even Toma. The character dynamics allow for hilarious moments (in Amnesia Later, the fandisk, that is).
3. Hakuoki: Quite a classic Otome game, I suppose. It’s was engaging because the storyline kept me interested most of the time. I liked all of them moderately. The art is also something that I am fond of. ^_^
4. Norn9: Nice art once again. With the number of characters, it can get tedious. I liked all the characters moderately, and the story mostly intrigued me.
5. Tokimeki Memorial Girls Side 3: Stat raising/ tedious gameplay is either hit-or-miss. Some love it, some hate it. Others like me, cheat their way through (*hides face*). For the first time in the series, all the main 6 characters are likable.
