This is basically a regression novel, where MC regresses due to a videogame invading reality. MC who in his first life had a common class was still considered as one of the best due to his commanding and production prowess. He dies and regresses to become stronger than before (obviously) and to find the truth behind the game and it's mysterious powers

His new class is (necromaster, yes it's different than necromancer). The game and it's elements also feel like what I would expect a AAAA (quadruple A) game with ai... more>> and gods to be like, incredibly detailed, dedicated fanbase, insane addicts, having more human npcs (with emotions and priorities) and insanely hard to master mechanics MOREOVER the guild, players, partners, rivals etc are also not one dimensional and have more personality than ai (the biggest+ point). Looking at the authors track record his knowledge about game and gamers is good enough that we feel completely immersed in the game instead of so many authors habit of underestimating gamers and using laziness, being unrewarding or being difficult as plot points to make stuff exclusive to MC. <<less
