The most IMPORTANT ASPECT is online, and the online battle is near flawless, the connection is well-done and lag is barely a factor in the game. The game gives your character personality and lets you play as a character you like not just on a fighting perspective, but on a personal perspective. Many fighting games lack this, even if its filled with your typical anime bullcrap, Hazama and Relius are very interesting and cool characters. The point being, the graphics are well done the controls are fluent, It is a must have.
This is a must have game for any 2D fighter fan, if you are into BlazBlu games or other Aksys games such as Guilty Gear, or even if you are new to 2D fighters this should be one of the first games you own on your vita. The upgrades to online play have been amazing from previous BlazBlue games as well, and unfortunately they failed to explain on the box art that it has online play so i went into it disappointed but was extremely happy and surprised to find that BlazBlu for Vita does in fact support online play and it is really really good.
If you're into fighting games and want something fresh Blaz Blue it's probably the best option nowaday and hell much better for the PS Vita, the gameplay feels more comfortable on the portable system than on the big guy ( PS3 ) , and if you thought that the graphics looked lazy , the portable system does some magic on the game. And the Extend subtitle is a genuine name for it, it really has many content that will likely be in use often. Just make this one a necessary tittle to your game library .
