I'm selective, but I do really really enjoy a good manga/anime. My favourite would have to be Death Note for its complex themes and plots and ultimately unique characters. The original season of Pokemon comes in second for the sheer amount of simple joy it brought, and continues to ha ha - I also like FMA (I have two nicknames at school - most everyone calls me Pride after that dearest of Homonculi, and a few call me L, from Death Note - yeah we're kinda dorky ha ha) - and even though there is now technically a manga, the Kingdom Hearts series is still more a manga-themed game, but I love KH pretty passionately too. I also was into Yu Gi Oh and have my cards (along with my Pokemon cards) - but yep that's a breif overview of my top favourites --
and sadly I've never had the opportunity to read any yaoi...
