Just reading those keywords above will let you know about 90% of the plot before you even read it. The manga does nothing to remix the genre and just repeats what has been done a million times ad-nauseum. The protagonist never suffers any major setbacks, knows everything about the game world, cute girls are drawn to him (and of course he teaches them how to be powerful), he collects things to craft, and the people populating the world are in awe at how smart he is.
On the plus side the reader doesn't have to suffer through him doing all of this when he is a child, the MC starts his reincarnation as an adult more or less.
