I don't know much about anime (except for death note, which squallion introduced me to, all I'd seen before was pokemon, digimon, and naruto, and while they're good for kids they're none of them the sort of thing I'd actually enjoy watching anymore. So I was surprised to find that death note is good)
/tangent
anyway, the only other one I know of and am interested in but haven't checked out yet is
Full Metal Alchemist. It also sounds like it fits your criteria, from the very little I know about it. (so if it turns out to be a book comic, very old, or a very limited series, etc., I'm completely (and blissfully, a lot of it is still crap imo) ignorant of anime, and can't be blamed)
Instead of asking here, you could just read Piro's newsposts, where he mentions like every anime ever made, I'm pretty sure.
