I bought the limited special edition...
You might think I'm a degenerate,
and you are not wrong.
But I have a Kurumi dakimakura,
and you ♥♥♥♥♥♥♥ don't.

Serious review below:
Since Date a live is an episodic, choice driven visual novel (VN) containing a multitude of routes depending on your girl choice, I'll review each part and route separately as I complete them. I'll keep it short to fit the character limit.

Rinne-Utopia
Girl/route rating: Rinne = Kurumi > Origami > Kotori > Touhka > Yoshino
If it wasn't obvious after reading the game's title - Rinne is the main girl of the first VN, she's the centerpiece of the entire story so saying I didn't like her route is saying I didn't like the game in general. Her route is the "true route" and fills most of the gaps in the story and while few still remain after the playthrough, she makes the entire thing mostly whole. Also she's voiced by the legendary Hanazawa Kana, making her one of my favorites.
Kurumi is probably the most interesting character based on her character traits, story and design. Her story was the only one, that didn't feel like "just a side-story" while the other routes were there just to occupy the reader until Rinne's route becomes available.
I like Origami's design and character, but her story wasn't anything special. I'm a sucker for cute, sassy sisters but Kotori's story also left much to be desired. Touhka is way too one-dimensional of a character for me to truly like her and Yoshino is just a bad character overall, besides that she barely progresses in character development throughout her entire story, making her part basically pointless.
