Oh wow, Anime is like my life so listing my favourites will be hard XD
1. CCS <---- best anime hands down ^^
2. Gundam SEED/Destiny <----- It's an awesome anime, and as Little Wolf mentioned earlier, it has awesome music. Besides, I'm a mecha fan w00t.
3. Inuyasha <----have all the DVD's in jap and some manga, I usually discover the manga after the anime so my manga/doujinshi collection is pretty small.
4. Dragonball Z <---- One of the biggest Gohan fangirls ever, until DBGT that is, one he got the glasses my fangirl-ism is totally gone.
5. Spiral <---- This anime makes my brain hurt, it has all these mysteries and all these side-plots, but I still love it, I'm a sucker for mystery animes.
6. Full Moon wo Sagashite <---- This anime is so sad and touching, at first it seems like the happy-go-lucky singer with all the fame problems, but then it gets so sad and unexpected, it's one of my all time favourites.
7. Witch Hunter Robin <--- I'm not much of the gothic type, on the contrary I'm the complete opposite, but this anime catched my interest, and it's really good.
8. Sailor Moon <--- This anime was my first anime ever, so it has to be considered a favourite, besides, I watched the all 6 seasons....twice.
9. Air <---- It's a new anime and it just finished, but it's so good, so confusing too. But I like it. But my god, it's the saddest thing ever >.<
10. Raxephon (sp?) <---- One of the most underated animes ever, but the movie was really good, and I like the music alot, after all Maaya is one of the best *hums Hemisphere* the anime is pretty good to, just not as understandable as the anime, as weird as it may sound. I got the 2 hour movie than a 26-episode anime, yes I am odd >_>
*looks over list*
You'd think I'd have one fav genre XD
