Fatal Fury: The Battle of Destiny: Rough, it's a more cinematic Street Fighter 1 instead of a SFII rip-off. It's still pretty interesting, and it's where a lot of SNK's unique style got started.
Fatal Fury 2: This is the SFII knock-off. It's kind of neat if only for how cool Krauser is, so play through it at least once. But in terms of competitive scene it's utterly overtaken by...
Fatal Fury Special: The SFII: Championship Edition of Fatal Fury. Adds in bosses and some extra characters, but takes out the story. The concept that would become King of Fighers starts here. It also has a good early example of SNKglish.
Fatal Fury 3: Absolute height of presentation, but it was not a popular fighting game. But man, that presentation. Introduces a lot of important story concepts, hidden behind a completely bizarre English translation.
Real Bout Fatal Fury: A slapped-together game made from Fatal Fury 3 assets, it's super smooth and fun to play. It's also the canonical end of the whole Geese arc, and it's worth a playthrough just to see that.
Real Bout Fatal Fury Special: They redid all the sprites for this one, it's also super smooth and fun to play. It's a toss-up between this and RB2 for the ultimate classic Fatal Fury experience.
Real Bout Fatal Fury 2: It's like Special, but tuned up a bit and with a couple extra characters.
Garou: Mark of the Wolves: The most SF of Fatal Fury games, it's popular with people who don't want to deal with the lane system. It's like SF3 in that it throws out almost the entire classic cast for a set of newbies, but unlike SF3 people like these guys. Worth playing if only to see how damn pretty it is.
By the time you hit around Real Bout you're looking at some of the prettiest fighting games of the 90s, so it's worth it just to enjoy that.
