Choosing one is too difficult for me.
I have favourites in most genres.
Therefore, I cannot give a direct answer to this.

.. It is too soon for me to say what my favorite all time anime is. Recently? I got into ToV: First Strike, along with me finally getting the next volume of Higurashi, when also put me back into it (First volume and second all I had.. watched half an episode on youtube.. :/) so yeah.

Tales of Vesperia: The First Strike takes place before the game (Obviously, hence 'first'). But all i've seen were trailers and voice actors (

Wolf's Rain is good, but it is being buried under new animes.. which is sad.

Bleach. Code geass. Higurashi

Bleach gets a 9.7 for me, Code geass gets a 10/10, Higurashi gets 9/10. All good.

Bleach is awesome... Sometimes, it's slow-pace and hardly endurable (..sigh, like the Bount Arc, but I guess without it, Nova would never had appeared, so i'm alittle grateful)... It also has a very beautiful Main Cast Character, Rukia-chan

I loved Wolf's Rain's storyline and plot. Though it became quite sad at the end.

The best anime i've seen as of late? Thats abit difficult, considering my mellow consideration in anime. Hayate the Combat Butler is good, Texhnolyze is good (so far, I don't have all volumes yet) and the anime I got my eye on isn't a series, it's a theatre movie, the first of it's called to be exact.

Tales of Vesperia: The First Strike

I don't know much about it, but Repede is a puppy, Flynn is in it, Yuri is rumored to be even more sarcastic in it then it's sequel, and some characters make an appearance (Rita, Raven... Estelle?)

....Repede as a pup.. xD! super kawaii!.. ._.;

A-anyway.. Wolf Rain should be remembered because of it's graphic masterpiecing, the voices (both dub and japanese) were good, and the storyline was good, though at times, I felt a fillar arc coming up, which frightened me.. xD
