Death March is oretsuueeeee, it's just amusing too. Unfortunately, I'm not sure the anime will get to the fun and amusing parts of the story - no High Elf, none of the dungeon characters, etc. They also appear to be inserting more combat scenes at the expense of story, like they did with Knights & Magic.
On the other hand, I love how the show does the User Interface bits, especially the "learned a new skill" and "used a skill" popups. More 'in a game' anime should use that sort of thing.
