@AstroCoke The problem with the Gamer is that they use the gamer system has an excuse when they want it. In one chapter, it's ridiculously OP, in the next, it's next to useless. I was really interested in it but as more and more inconsistencies appeared, I started to read with only one eye.
Two good example: level: at the start, level is the equivalent of power level of the people (except for the "Gamer"); but eventually they can increase their stats without increasing level, with just training. Said training that increased their level before.
Craft: The "Gamer" is supposed to be, ... well, a gamer. So, when he unlocked the craft skill, he should have experimented with it a lot. But finally, craft is only used a lot later.
