I've read up to volume 4, and sincerely await more. KMTS owns, their releases have been every couple days (they say it will now be slowed down to maybe 1-2 times a week from here on out, but that's still way more often than most series, of course...).
The structure of plot developments is truly right out of an RPG; you don't find a lot of unique objects or situations in the story. There are treasures, elves, dwarves, innkeepers, taverns, thieves, mysterious orbs, a bashful dwarf and an incautiously brazen yet kind-hearted warrior. They discuss tactics in terms like you'd see in an RPG (like how mages are usually slow, and need to keep their distance to let the "melee" warriors in their party act as a shield). Most conversation is deus ex machina, like in an RPG.
Why do I like this series? First, just because there are cliched plot elements and no subtlety in storytelling doesn't mean the story is bad. Even if I've seen similar story elements before, they're combined in unique ways and I still can't predict how it will turn out. And no subtlety serves to allow you to easily follow what happens in the story, which is nice and convenient. Second, fan service (<3 elves). Third, the characters. i know I said they're cliched, but I still love them, and they surprise me. They're not static, but they're not predictably dynamic either. They influence each other in surprising ways.
Fourth and most of all, the main character. "Id" (trap) is very mysterious. He's someone who values companionship but still keeps many secrets to himself. He sometimes seems too aloof but he's capable of "cute" reactions. Well, I shouldn't talk too much about him.
So yeah, I read this for the main character, character intrigue, and because everything about the story is in general, well, entertaining.
