Akagi and DN are both strongly psychological anime. At a glance, they're not quite the same, but if you keep watching you'll find out that Akagi is not only about mahjong. Both Light and Akagi are genious in what they do. What's more, it's surely same vibe here and in DN, though it's of coure not as dynamic as DN, you have to be patient sometimes and "wait for a better times". Still, both is Madhouse work, so you won't be dissapointed.
