The first link had an introduction, which was IAHgames SG promotional video to the english explanation which the youtube link provided was in korean. Well many players had much to look for in the 2.0 release and many players which I think should give 2.0 a try. If you thought in some way that SG GE in closed beta was a bit of a grind with it's experience percentage well in 2.0 shouldn't really have that problem.
