Here is my review after reading 189 chapters :
MC have a lot of broken skills, know everything in the game (boss skill, dungeon environment, future event) with excuse as 'beta player' and MC is the only 'beta player' in the game so far and no one in his party care about something like that, they just follow MC command like trained dog and ask him everything about the game. Even the game company don't care about MC, they should be atleast suspicious but they just don't care at all.
Someone in MC party always make boring dirty joke, there are 2 money grubber who love to hoard every items and money as much as possible eventhough they are filthy rich, MC meet 2 new member (1 with 'perfect leg', the other one is another *** joke lover).
Author always talking about how sexy and big boob the healer in party, and keep creating pointless argument againt each character with end result as dry humor, mostly *** joke humor then everyone laugh like middle school boys.
Female MC protagonist which never appear again after 1st appear in early chapter with short introduction.
Dumb and idiot antagonist so far, there is 1 rival guild who hate MC, and the Guild Master from tha guild always know how to make fun of himself like idiot, he is so shameless as well.
Story so far mostly doing dungeon run, gathering materials, errand boy, there is no notable story. Even the main quest which MC got only doing dungeon run and kill boss in the dungeon. Game world itself never get explain so far, so I don't know how big the world is or what place in the game world. MC rarely do anything in real world.
