In South Korea a lot of (maybe even a majority of) PC gaming happens at "PC bangs",pretty much a LAN gaming center/internet café where you can play for a small fee per hour. I wouldn't be surprised if the devs simply meant that the PS4 version is superior to what you can play on a standard PC from a PC bang.
By now KUF2 afaik is a f2p MMO and the PC bang crowd should be their main target audience.
