Barry - depends which route you'd like to take.
If you're not bothered about seeing how the games have developed and experience the different moves and charging systems of the earliers games go staraight to '97 or '98 as they're without doubt the best two of the series so far.
If you really want to "experience" the KoF series start at '94 and work your way up.
Despite not having team edit '94 is a top game and has some of the best backgrounds and music in the series and is still a solid fighter.
'95 is a bit dodgy in my opinion. Graphicaly it's very very good for its time but it's wickedly hard and this spoils it for me. Definitley the weakest in the series.
'96 is brilliant. The characters really start to evolve move wise and it's a lot deeper than the other two and includes the superb "Boss Team" of LWK, Geese and Mr Big.
'97 is even better (and the best imo). The lack of true bgm on some stages is disappointing, but the presentation is outstanding!! More moves too and a very solid fighting system especially with the new power-up gagues. You can't go wrong with '97, it's superb from start to finish and Orochi is not as cheap as pervious bosses (but still no push over).
'98 is as good as '97 in terms of fighting but the overall game seems to be lacking something over '97. Loads of teams to choose from so plenty of team editing to be had. Many argue this is best of the series, but I feel '97 edges it (just). Rugal is cheap as fuck and a real bastard to beat.
'99 is a disapointment. The new characters are lame as fuck with exception of Whip, who is great if you've got the patientce to master her. Fantastic graphics and some really good backgrounds. However, SNK messed around with a lot of the familiar moves on the more popular characters (not good) and there aren't as many fighters to choose from. The Strikers system is a new innovation, but is fairly pointless and doesn't add a lot to the game.
Krizzalid is a bit of an arse to best, specially when his energy is low, but he's not as bad as '98 Rugal. They ruined Terry in this game.
2000 - improves on '99, but more of the same, the Strikers system is better but still pointless imo. The only real improvement is K', but I don't really like him anyway. I would strongly advise not to start with 2000 or '99.
2001 - Not played it, so I don't know what to say. Looks good, but that doesn't mean it IS good.
Hope this has helped you out Barry.
