Epic Fail (guffaw) Store Sale (Korea specific?)

So, after randomly checking out the Epic Store today it appears some unnamed sale has launched, at least in Korea.

Some of the games (admittedly there's only a few available anyway) are heavily discounted - the new John Wick Hex game is 70% off before it's even been released (a sure sign of quality, amirite?).

Hades is down to 6,000 won (from 20,000 won - 20 or so US dollars).
World War Z which is alleged to have sold amazingly is already practically half-price.
Outward is, again, practically half-price.
Subnautica is down from 25,000 won to 6,500 won.
But the crown jewel of discounts surely goes to Hello Neighbour Hide & Seek...down from 30,000W to a paltry 4,000W.

UPDATE: Store has now added a banner regarding the sale which, in a display of earth-shatteringly epic creativity, they're calling the "EPIC MEGA SALE"......sale ends June 13th.
