From Tokyopop:

In real life, Roto, Boromid and Ah-Dol are average kids with average problems, but in the virtual world of Lost Saga, they're heroes. They might even become legends... if they can stop bickering long enough to level up. Whether it's werewolves running rampant or a gorgeous pair of troublesome thieves, our boys must be ready for anything, because in Lost Saga nothing is what it seems and murder can happen with a click of a mouse.


The series centers on the main character Jang-Gun and his friends along with their virtual reality avatars in the computer game world called "Lost Saga". When Jang-Gun logs on as a different character, he "Creates" an AI with a personality from the hacked disk he found when renewing his appearance for his once a year renewal process. Yureka is a flutter-brained, but advanced, AI with powerful stats and a real-life doppelganger. It is his turn to see just how deep his immersion in the virtual world goes.

Nice manhwa

At first I thought it was just another stupid RPG manhwa, so after reading a couple of chapters I dropped it. Recently, while looking for something new to read I noticed it had many releases, so I decided to give it another try.
24 volumes later I can tell it's a really good piece of art. Most of the events take place in a game, so you can enjoy the fantasy world, but every once in a while you get back to the reality, which adds a whole new world and set of characters (not many though, it's weird how all characters from game meet in the real world) to enjoy.
Some characters are a bit naive (genius hacker who sometimes acts plainly stupid), but I really like current development, so I can forgive author for that.
It's not on the level of One Piece, Claymore, Kekkaishi or Alive, but a good read nonetheless.

I am familiar with those strategy since I love playing rpg. The protagonist is quite evil and funny ^-^ I am now in chapter 39 and I will finish this amazing manga first-time reading this kind of manwha that is base on morpg. Read it and you'll love it.

Have to agree with most of the post here. Really a good Manwha and has a nice story. Like how it shifts from Volume 16-19 to a different plot as far as I can tell. For anyone who's been eager to read the latest chapter of Yureka, there seems to be a underground translator group that only uploads their chapters to mangafox dot com and seem to have up to volume 30 ready for translation. Can't wait to read more =) Enjoying it to the fullest

This is by far deserve to be one of my top tier manhwa. Parallel worlds manga always interesting me and game based one are the most entertaining due to easy interacts between two worlds. That explain my passion for .hack series and this manhwa definitely do a good job. Lack of fanservice, as the guy above said, but the comedy do wonderful jobs to cover on that. The only complain i can possibly have is the scans. From the first chap, we already experienced chapters skip, even in one volume. And now, vol 19 after vol 6 confused?? Seriously, WTH

Wow. Just fantastic. I love reading game-mmporgs based manga and this one did not leave me disappointed. So far, the action is all fast paced; leaving my breathless. I found this manga today and I've been reading nonstop until 4:50 A.M. Plus, this is so good that I'm not even going to the bathroom although I really need to pee because I decided to review and hopefully persuade others to read this. Although this manga has pretty much no girls with half naked dresses barely covering their top, (lack of fanservice) but the action makes up for it. Definitely recommended for fans of 1/2 Prince and .hack.

Ah yes. I forgot to mention that Rotto, Lotto, however the hell the translators feel like spelling his name, is QUITE evil. He will manipulate friends and allies to get the desired goal. However, for some reason the reader sympathizes with him because although he has a bad personality, his passion for winning is tremendous and garners a lot of respect.

Certainly one of the best manhwa that I was able to read. After the 16 v. begins the second arc, is more darker that the first but explains the mysteries behind this series, surely at the beginning not so funny as the first but after a while I started to love it the same.
The only flaw is the fact that the scans are slow to die, so i hope that someone begin it someday (1ch in 1year is absurd for a probably 30+ series, unless you can read the French version xDD)

It's still one of my favorite but it became a bit strange after v16. Completely different, and I think it's become quite lame...

One of my most favorite series in both manwha and manga. I even went and bought them in French because more have been released in French than in English.
