This is okay, but the 2nd is better
The graphics aren't the best, but I'm not complaining about them. For many characters, you can do bankai transformations which is pretty cool, but a downside is that it only lasts for about 20 seconds. Some bankais really pwn like Hitsugaya's and Komamura's, but some really suck like Ichigo's Tensa Zangetsu. I was quite disappointed by how much Ichigo's bankai sucked. Renji's Hihio Zabimaru also kinda sucked, but it's better than Ichigo's.
Another bad side about this game is that it kinda gets boring if you play by yourself. Multiplayer is a lot more fun and will last you a few more hours of gameplay. I haven't played the second one yet, but by watching videos of it, it really looks better than this one. I'm not trying to imply that this game is totally bad, but if you really wanted a Bleach game, I would suggest getting the 2nd. After all, the 2nd features characters that are more recent to the Anime. In this one, do not expect to play as any of the Espada, because it's just characters from the first and second seasons.
I may get the 2nd...eventually.
Buy this game if you want, but I personally recommend the 2nd. Just make sure you can play imports first before you waste your money.
