KOF99: Lame Striker System. almost useless completely.
KOF2000: fun striker system. can call striker at anytime. in the middle of a combo, before being attacked (for setting traps) .... etc. some combos are missing
becomes annoying when played by experienced players who can pull 100% combos easily.
KOF2001: Striker system toned down (slighty more useful than in 99). two new gameplay systems interduced:
- cancel system: cancels super moves by desperetion moves, which take 2 power stock in exchange.
- the wire effect attacks: certain moves and super moves cause the opponent to bounce to the wall and fly back toward you, giving you a chance to add an additional attack/s.
the gameplay is faster now. all characters have chain combos now (strong punch --> weak punch or kick --> super move)
KOF2002: Strikers removed completely (3 vs 3 again). 80% of wire effect attacks were removed. cancel system remained intact. gameplay is even a little faster than KOF2001. many chain combos were removed again. feels like a fast KOF98.
KOF2003: each match consist of 1 round only. that means once a character is defeated, the next character directly jumps in and the battle continues WITHOUT stopping. you can change between fighters during a match by pressing B+C or C+D. the character will perform a pose and exit the screen, and the other character comes in. but .... during the pose, if the character was hit by an attack, the tag will be cancelled. so you must becareful before switching between characters. however, there is a new / another tag system, in which you can swtch characters safely, AND A CHANCE TO ADD A FREE COMBO in exchange of one power stock:
with any character, do a [QCF B+C]:
- the game will pause for few mille seconds and a flash effect will appear (similar to DMs)
- the chatacter will perform the regular C+D attacks that were in PRevious KOFs. but this attack will have HIGH PRIORITY over most other attacks, it will be done very very quickly (as soon as you press B+C).
- if the opponent was hit by this attack, s/he will be stunned till the other character comes in, giving him a chance to attack the oppnent with a free combo.
good luck with understanding all that rubbish. sorry but my Engrish sucks and I'm working hard on improving it. I can go on with more detailed info if needed. let me know whick KOF you're interested in hearing more about it.
