I alternate between video games (mainly RPGs) and anime, with radio 4 in between. Variety is the spice of life.
While playing Rogue Galaxy (80+ hours) I also watched Cowboy Bebop, Guilty Crown, Infinite Stratos, Durarara, Baccano, Kiseijuu, Aria, FLCL, Hitsugi no Chaika, and half of Shou. Some games are long. (Oh, and I haven't necessarily read the specific manga, as opposed to its anime, in favorites.)
...and how else to 'conclude' the 30th day of anime than by watching Ayakashi/Mononoke, a very psychedelic anime...
(ps. hallucinogens + anime, match made in heaven. Mushishi being probably the most apt.)
