Wacky antics force the lonely girl in class to hang out with the new girl in class and learn about fun. Also Euro-style board gaming. Subject matter aside, the visuals are middle shelf and the protagonist has no agency. She’s simply dragged along by the plot and other characters because she’s there.
As for the subject matter… I play a lot of board games, including almost everything shown in the shop. However, I’m not sure I get anything out of highly detailed box shots and the friendgasmic high school girls discovering them?
Dice Club lacks a compelling story structure and protagonist. Unless you really get something out watching people play and explain board games, this is no different from any other ‘did you know’ / ‘public access’ vibe anime.
