5 stars: Its a good game but has a big learning curve for serious players. Multiple gamemodes all kind of different and fun. Summons can be unforgiving most of the time but still will get good stuff. And the game could use more event quests and ways to grind items used in powering up characters. Needs more ways to get gems for the summons.
5 stars: Having experienced a few gacha type games, it came as a surprise how accessible this game is to new players. The crew members are as colorful and energetic as ever and the story retains its roots in a simple, yet effective structure. The game also possesses a unique approach to combat, with type variations and vast pirate crew combinations and bonuses for structuring them well. And remember, it's One Piece; take your time and enjoy it.
4 stars: It's good, animations are awesome. The best thing is that you receive a huge amount of loot at the start, including many limited characters, but progress slowly gets hard to achieve once you reach higher levels. Also some game play do require rainbow gems, so save up for those while you can (they aren't as hard to get at first, but they get basically impossible to collect)
3 stars: Good so far. Edit: Downgraded to 3*. The game gets boring after a few days playing, not a lot of content to play and the content available has quite a high difficulty spike. It has amazing graphics and good story, due to it being pretty much the One Piece plot, however to progress takes soo long, it is...
