I haven't watch anime in agesss so I can only recommend old anime. I really like Hunter x Hunter (very old anime - think dragonball style of drawings - with several series) and Honey & Clover (nice drawings but think it may be smt females rather than males would like).

Have you watched Halo Legends, it is based on the Halo game and it is made by various famous anime artists, it is a standalone movie, also watch anything by Hayao Miyazake and Studio Ghibli, Akira is a must see classic also as is Ninja Scroll... Have you watched Aachi & Ssipak
