How did they create this Game?

I was just hovering around the Web like usual. I see Blades of Legends, so I click it, it sounds interesting. I'm like "WOW! What kind of RPG Game is this?" And I start playing it for about a couple of hours (still level 1). Doing a bit of Battle and some Quests. Very interesting there is no such avatar like other RPG's or MMO's. I see all my Stats at the left side of the screen. There is a little chat screen below so you can chat, you'll need to get some kills to be able to chat (FYI). So after all that I wonder how did the creators create this master piece. It's a very unique RPG Game in a different way. I think I've played one of these types before, but this is something else. So the question is how'd you create this game, and if so what is the name this type of RPG Game?


P.S. If this Thread is in the wrong section. Please let me know and what section would be right for this.
