I thought it was really popular, and I enjoyed it. I was one of the first few to hit max, and I remember selling off about 1k~ gold about a week into it. I really didn't like the end game, at least at the time, the dungeons were impossible and we had to take various jumps/glitches/paths just to avoid fighting . When it switched over I somehow lost my account, and couldnt log into the NA servers, or the kr ones and my account just dissapeared so I stopped playing, my sister was a beasmaster and my friend a Knight.
I remember there was about 4~ hour span where the quests were redoable , it was so much fun.
