From the review, "Street Fighter IV is expensive - $59.99 for the PS3 or Xbox 360. Meanwhile The King of Fighters '98 Ultimate Match, with 64 fighters and tons of gameplay modes, only costs $19.99. On top of that, you're getting the chance to play a historical game which didn't get the respect or release it deserved in North America when it was originally released. Not to mention it has retro charm, especially with the NeoGeo The King of Fighters '98 ROM built in.
Just because something is old, doesn't make it bad. The King of Fighters '98 Ultimate Match is a classic fighter. It is going to challenge you and make you appreciate how wonderfully hard-core the original game was. It may not be as flashy as current fighting games, and the computer controlled opponents may be unforgiving, but fighting fans would be remiss if they let this release pass them by..."
