Hard, but still fun.
The first thing you will notice about this game is how much eye candy it has. I guarantee that. The backgrounds in the game are so lush and full of life, you could probably stare at them endlessly, just to see everything that's going on. The characters in the game are also very, very nice. They all seem kind of hand-drawn, and it's like watching an anime show! However, they're EXTREMELY anime-styled, so if you don't like the idea of a cat-girl, I don't think you'll appreciate the art as well as others may. Being an anime fan, though, this really isn't an issue for me.
Another great thing about this game is its soundtrack. I never really got a chance to listen to a lot of the background music, but from what I CAN hear (past all the yelling and fighting) and what others have said, it all sounds pretty good.
Now, about the meat of the game. What is it, you may ask? The gameplay, of course! As BlazBlue is a fighting game, it's fairly straightforward. Two guys (or girls) go and beat each other up until someone gets knocked out. Of course, it can't be this simple. Otherwise, it'd be no fun! What makes BlazBlue so different from other fighting games, however, is... well... just the uniqueness of each character! For example, if you were to play Ragna, a character with straightforward, easy combos and the ability to siphon others' life, you won't use the same tactics as when you're using someone like V-13, a character with amazing long range capability and quick speed. Everyone is just so different. You HAVE to learn everyone ONE BY ONE. What everyone is capable of, though, is still quite amazing.
You may have also noticed that Ragna, the character I just mentioned, can suck the life from others. That is no lie. In fact, every character has a unique ability associated with one of their attacks, and the ability perfectly complements the character. For example, Ragna, who can siphon life, has great close range capability, so it suits him well. Another character is one named Iron-Tager, who is highly immobile, but is able to magnetize others, just to compensate for his poor mobility.
Moving on, there's still even more about this game that impresses (this'll be short though)! The pacing. It's all very quick and frantic, so it can get overwhelming at times (what with all that's going on), but it's still a very fun experience.
There's also some online play. You know, so you don't have to go to the arcade every time you want to play someone else. From my playthroughs, the online play was very, very smooth and there was little lag going on. The fights were intense and fun (except when I lost, which was a lot) and the online is just great. Also adding to the replay value is a story mode. Not just any fighting game's story mode, though. BlazBlue's is different. Each story mode is different and unique, and for once, this whole compilation of adventures actually forms a STORY. Not to spoil too much, but Ragna, the main character, apparently has ties with most other characters, and everyone is after him for some reason or another.
In short, BlazBlue is a fantastic game. It has lots of eye candy, replay value, and the in-depth fighting system can surprise anyone. However, it IS pretty hard to learn, and the art style can be a little too anime-ish for others. Overall, though, I think this game is one any fighting fan can't put down.
INFERNO DIVIDER!!!
