[Random VNs: Plans for the Year]

Ummm... there is no Otome series by Ensemble.  There is Koi no Canvas and its fandisc and Gokigen Naname, which are excellent games.  However, most of the rest of that company's games are of... mixed quality.

How is there no Otome series? http://www.ensemble-game.com/13.otoiro/download.html If you check this video at 1:21 they mention "Otome series" and even feature girls from each of the series' games. It's not a series that shares characters though, its just games with a similar premise of the trap protagonist.

What about replaying the entire Otome series by ensemble(including the fandiscs), as a new game is coming in March and apparently it will include characters from previous games as guests.
