I've played Genshin Impact since Day 1. And I still vividly remember the first time I saw the cutscene on the first Statue of the Seven. It was like literally playing an Anime, not an anime based game. A LITERAL ANIME.
At that time Genshin Impact in my opinion shaped how game design should be approached. Because it was visually pleasing, that any other anime game genre paled in comparison.
To this day, with the release of the Sumeru region. Genshin Impact stood up to the next level by making critters and enemies interact with the environment. With just the shear amount of effort into making players enjoy the world of Genshin, still solidify this game as the most visually stunning.
