You gotta hand it to snk. 2k2 could have been the last neo kof. A return to the 3 on 3 formula, return of favorite characters, it didn't go out of the box, it was a dream match - a celebration of what kof was on the neo up to that point.
2k3 took some risks and changed the formula with the tag battles, threw in a ton of new characters, and launched an entire new storyline. I found it exciting and interesting, and an unusual way to end the series on the neo. It was also neat to see the neo doing 3 on 3 tag battles. There had been fan speculation that the neo couldn't do that sort of thing, which is why kof had always been a take turns team battle mode rather than the well liked tag matches of several of the Capcom fighters of the time.
