Nice upgrade to 2002.
As for the graphics, with the new atomiswave software get a good deal better overall, including the character sprites. The sound stays the same as 2002 except with new music. K9999 and Angel are missing but Jhun Hoon and Saisyu are added to this all-star roster. Mei Lee is also missing which brings the character count to 43. The boss in arcade mode is now young Geese Howard. There is no text in the cutscenes, so not story. The other modes include endless, training, versus, etc. Same modes as in 2002, and gallery of course. Also, online mode returns, but it is much clearer and faster this time, this brings the games value up a great deal.
Any fan of King of Fighters like me will certainly buy it. If your not already a fan of King of Fighters and have played 2002, then there is nothing to make you get into this one. Finding a way to play it is a must. It should be at least rented because it is old-school fun.
