• The game in question

Fatal Fury: King of Fighters, the 1st one in the series also directed by the same guy that made the very first Street Fighter. Since Fatal Fury became one of SNK's most popular fighters, characters from it would appear as part of The King of Fighters '94's cast, most specifically Terry, Andy and Joe... but there are some characters from here (like Duck King, Billy Kane, Raiden and most of all Geese) too that would later appear in other KOF or SNK-related games.

• Story

In 1981, Terry and Andy were brothers who were orphans raised by themselves in the streets of South Town. They were adopted by Jeff Bogard who was a martial artist. A few years later, Jeff got killed by his rival Geese Howard, a ruthless crime boss who rules South Town's criminal underworld and would kill Jeff because he would try to expose his criminal activities.

Terry and Andy made an oath to spend a decade training themselves before battling against Geese. Terry decided to wander in his home country, combining his street fighting techniques and the Hakkyokuseiken fighting style, taught by Jeff and his mentor Tung Fu Rue, who is the shin-fu of both that and the Bajiquan martial arts. Andy decided to perfect his own fighting style in Japan, being taught the Shiranui-ryu Ninjutsu and Koppôken, a form of empty-handed combat.

A decade later, Terry and Andy would reunite and, after the brothers pay respects to Jeff's grave, they encounter and befriend a Japanese Muay Thai champion named Joe Higashi from Thailand, and also learn about the King of Fighters: South Town tournament hosted by Geese. They enter said tournament defeating multiple competitors, including Tung Fu Rue who wanted to test the brothers out.

Canonically, Andy and Joe ended up being badly injured after their fights against Raiden and Hwa Jai respectively, leaving Terry to face off against Billy Kane, Geese's right-hand man. After Terry won and the tournament was over, Andy returned to Japan to continue training while Joe traveled back to Thailand to continue his own too.

• Mechanics and pretty much how to play the game

Mechanics: The game is awfully simple, you can choose between Terry, Andy and Joe and choose 1 of 4 competitors to start your run against. You can walk, block, jump and attack. You have 3 buttons to use: Punch, Kick and Grab. In some backgrounds you can also go to the other side of it in battle if the enemy does it first. After beating a certain amount of competitors, the game itself teaches you about the special moves for the character you're using, which here they are called Fatal Blows.

Difficulty: The CPU is messy and, although a bit hard due to the damage their attacks deal, they have certain patterns that can lead them to be easily cheesable, the damage is horrendously big to the point you can end the battles in less than 20 seconds, so with a bit of patience you eventually get to beat it

2-Player Content: The game allows for you to battle against another player in a 1v1 battle... pretty generic, right? Well, if the 2nd Player joins while you're battling against the CPU, they will join the battle with 1 of 2 characters and, after the match is over, it will get back to the 1v1 battles. This does not apply against Geese, so you wil have to do it on your own.

• Region Difference (List of changed move inputs)

Just to note that ←+↓, ↑+→, ↓+→ and ↑+←and similars mark the diagonals

They changed the required motions and inputs for one of the localizations and console versions, US is self-explanatory, JP ones also apply to console versions.

Terry's Crack Shoot: ←+↓ ↑+→ (US) / ↓← ↑+←(JP)

Andy's Hishoken: ↓→ (US) / ↓← (JP)

Andy's Shoryudan: Hold ↓, ↑ (US) / ↓→ ↑+→(JP)

Andy's Zaneiken: ←→ (US) / ←+↓ → (JP)

Joe's Hurricane Upper: ↓→(US) / ←↓→ (JP)

Joe's Slash Kick: ↓←(US) / ←+↓ ↑+→ (JP)

Every other characters only became playable in console versions

Judging by the changes, it seems that while the US localization commands where more unique (and also eventually would become the norm in KoF games), JP localization and console-version commands were made to be more universal and friendly
