Hunter x Hunter: Greed Island, Yu☆Gi☆Oh! Duel Monsters Recommendations
They both are about games.
its really Similar with the noah ark off yugioh
and in both series there try to collect cards
In Yu-Gi-Oh!, there is an arc where the main protagonist ends up in a video game and must clear it in order to get out. It is quite similar to the Greed Island arc, because the main characters have to clear out a real life video game. In both games, the goal is to collect rare cards, which have special effects than can be used to give users an edge in battles. Also, both anime give a similar vibe, and they are based on manga published by Shounen Jump.
