During PlayStation Korea's press conference currently being held before the opening of G-Star in Pusan, Sony announced several PS4 games by 25 different Korean developers.

Below you can see the full list of developers involved:

And here are the games. A couple are marked as "title pending" for now, since they were written exclusively in Korean.

Operation 7: Revolution

KIDO: Ride on Time

Quraré: The Magic Library

Title Pending (by QuattroGear)

Lift Car

HeroHeartsZero

Title Pending (by Buff Studio)

Starry Nights

Thumper

Heroes of Fortune

Title Pending (by Nimble Games)

Blade Warrior

Retsnom

Smashing The Battle

Mike & Milkbox

Title Pending (By Them Corporation)

Mortal Blitz VR

Racers:Dirt

Timing Hero

This definitely looks quite a varied line-up, spanning basically every genre known to man. Korean developers have always been quite creative, so I'm definitely interested in seeing how many of the games announced today will make it westwards.

Update: Below you can see the trailers for Operation 7: Revolution, KIDO: Ride on Time and Quraré: The Magic Library, and a sizzle reel for the rest of the bunch, recorded from the livestream.
