One of SNK's best games.
The technical aspects of this game are top-notch, thanks to the power of the Sega Dreamcast. Each stage is filled much much activity, color, and detail in the background. From Terry's stage where you are battling on a moving train, to Kim's stage of all his contemporaries watching him fight and react to fight at hand, are a few examples of the many sights you'll see as you battle. The voice acting is top-notch in this game, as each actor does a great job expressing the character's personality. The music for the most part isn't that great, but that's a small complaint with the game itself.
The main highlight of this game is the gameplay. One of the things that SNK did to enhance the gameplay is to simplify the command controls to execute a character's special and super special moves. A typical SNK fan know how complex some commands are, so it's great to see moves simplified. This also allows the fights to become much more aggressive and frantic as moves are going to be executed quite frequently during a fight. Luckily, the Dreamcast controller is quite responsive in commanding your characters, since you'll be busy at the controls and keeping pace with the fight at hand. Other gameplay additions, such as the T.O.P. system, gaining health when blocking an attack at the right time, and canceling a move to link it with a super special add strategy into your fights. Knowing how to take advantage of those aspects of the game can really take fights to a whole new level.
Being an SNK game, playing through the story mode, even through easier levels, are still quite difficult. So you'll be spending some time in practice mastering your skills before you'll see success. Also, there isn't a lot of extra modes to tide you over from the regular one-on-one bouts. Those gripes aside, as long as you give the time and effort into this game, you'll see why it's one of the more respected 2D fighters around.
