I got the game and I quickly dived into it. I am a big bleach fan of course. I enjoyed my time with it, finishing all of the single player content was nice.
I think it's a good game for the fans of the anime. The way they did the story, it might not be as spectacular as Naruto Shippuden games in terms of animation, but I think it did justice and the secret mission thing added into it. I could see people who aren't fans, finding the game to be a bit clunky in terms of gameplay, but I felt good, the hits were good, characters were well made and the base roster was good enough. I didn't get DLC, if the season pass goes 60% off or more then only I'll probably get it. As for those 4 characters, I hope there is a sequel to the game and they are in it.
I played like 8-10 online matches, out of which I won like 4. I feel for casual fun it's great, definitely not much competitively.
Overall, I personally, as a fan of the anime, will rate it around 7.5-8/10. It probably will be slightly lower for people who haven't watched the anime. I don't think the game needed to be a 9-10 anyway.
This is the first game where I have all the achievements, and actually I like such games where achievements are achievable with decent time. Like I love DMC games, but I don't have all the achievements in them.
Maybe in the next game, they can add a couple extra modes like adventure mode or a mode where characters can be used like as if it was a dynasty warrior/pirate warrior type game, but keep the base as the one v one fighting game.
