Crest of the Stars, PlanetES.

I only meant to recommend the above two but I went through my anime list to find some others that, if I remember correctly, should be okay as well.

Toradora, Usagi Drop, Kokoro Connect, Natsuiro Kiseki, Kimagure Orange Road, Ichigo Mashimaro, Potemayo, Kimikiss, Welcome to the NHK, Zegapain, Full Metal Panic and Fumoffu, Hantsuki, Canvas 2, Honey and Clover, Tetsuwan Birdy Decode, Higurashi, School Rumble, Kamisama Kazoku, I''s Pure, Lain, Maria-sama ga Miteru, general all/most Studio Ghibli movies recommendation, K-on! jan-jaka-jan, Karekano, Fancy Lala, Mitsudomoe, Narue no Sekai, Mahou no Chocolate, chu2koi, Fireball.

...and while I'm at it, you might as well watch Total Recall, My Little Pony: Friendship is Magic (skip the first two episodes if you must) and Seinfeld.

I'll mention Mizuiro Jidai as well.

I've watched so many I've begun to forget which ones I have watched.

I did watch the first season of Attack on Titan and thought it was well done. I just last week finished all 276 episodes of DBZ, a show I've always been curious about, but thought it was too childish to entertain me. It was pretty childish, but I rolled with it and it was alright. After Namek it did seem to go down in quality somewhat, but I also liked the development of Vegeta throughout the whole series.

A few favorites that haven't been mentioned yet:

Claymore
The Twelve Kingdoms
Code Geass
Macross (all of it, though Plus is kind of odd)
The Last Exile

I used to watch a lot. From the top of my head:
Dennou Coil
Baccano!
Kara no Kyoukai
FLCL
Haibane Renmei
Kaiba
Gankutsuou
Kino no Tabi
Mushishi
Tengen Toppa Gurren Lagann
Shinkai Makoto movies

LOL!! awesome post!!! Kirosa! And great picks and lists everyone! Keep them coming!!
