5 stars: Good game, lots of fun skins for your favorite characters. The rumble pvp is pretty nice, and there's challenging missions that require tactical thinking about your team setups. Also not p2w, you get quite a bit of gems for pulls, and don't feel particularly short on resources. There is an energy system, but it's been more than full no matter how much I play. The game is a little overwhelming in the beginning, but keep at it.
5 stars: I like one piece, and the game has a lot of interesting mechanics which are fun to mess around with. The sprites and animations are also pretty cool, and it's not even that pay to play; you can get max special and level without having to pay which is refreshing. Overall, I recommend
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: pro: fun game, many mechanics to learn, one piece con: the newer events are structured to where you need new chatacters to clear otherwise it is very difficult; wish they would make it where it can be reasonably cleared with older characters if you don't pull on new banner (even if not boosted). also make it where a lot more older characters get reduced specia...
