Grand Adventure looks like any faithful anime adaptation does. Cel shading dominates the game’s style; no real shocker there. While the environments could have been made a little more memorable with additional detail and interactivity, what’s there works extremely well. Perhaps what is more important here is the animation. Most anime features a very unique flavor of animation. Crazy directions, melodramatic poses, this is what people want and expect, and Grand Adventure is also faithful in this respect. Your characters battle their way through the One Piece world with fitting flamboyance.
Audio is equally important to the experience, with the use of sound effects and voice actors straight from the show being a necessity for a faithful experience. Here too, Grand Adventure delivers.
