D-Frag!, Nana Maru San Batsu Recommendations
In both animes you will have games and hobbies as the main topic. School clubs are the places these game-otakus will meet.
While in D-Frag! the gaming club already exists and shows on a hilarious way their obsessions with everything related to every existing game, in NMSB they want to resurface the quiz club. It's very interesting the fact all the characters in both animes particularly have different interests but an objective in common.
D.Frag! is funnier than NMSB but both really enjoyable.
