Not exclusively!

Witch Hunter Robin, FLCL, and Blood+.

I actually would really love to watch the later seasons of Sailor Moon, as well...

One Piece is still the only series I have stuck with since I started it. The author is just great.

Anyone ever seen the Guyver anime? Brothers friend would bring it over, that was my first real anime I think.

Ruroni Kenshin is also a good one. That is quite a show. If I think of more I'll post them.

Oh man there are way to many good ones for me to say I have a number one favorite. I'll just pick my top three of this moment.
Yu Yu Hakusho
Cowboy Bebop
Eureka Seven

1. FLCL- I doubt I will ever find something else with so much replay value or so enjoyable to simply watch regardless of the writing. The writing is clever too though and I could spend all night raving about FLCL but I'll stop here.
2. Cowboy Bebop
3. Fullmetal Alchemist (and Brotherhood)- I cheat and count both series as my third favorite. Both series have their issues but they complement each other very well
4. Paranoia Agent
5. Eden of the East and movies

My favorites list has changed quite a bit since I last posted here.

Crest / Banner of the stars
Ghost Hunt
Clannad
Amagami
Dance in the Vamire Bund
Samurai Girls

Huh, I've not posted in this thread yet.

I've not watched much, but I've pretty much like everything I have (with the exception of Neon Genesis Evangelion and Paranoia Agent):

* Claymore
* Code Geass (LotR and R2)
* Cowboy Bebop
* Death Note
* FMA (& Brotherhood)
* GitS (SAC and 2nd Gig)
* Gungrave
* Samurai Champloo
* Trigun

Favourites have to be: GitS, FMA, and Death Note.

I got around to watching Deathnote (badass but way to short)
Bleach, I didn't get very far into it, but I saw the most badass fight I have ever seen in an anime (when he fought the dudes brother in the very beginning of the series)
and I finally watched some Naruto, which I got really into
