The main character is so overpowered as a max level rpg player gone full "no lifer" he owns every rare epic legendary godlike item that has ever existed in the game, nothing is a challenge, he is pretty much the Sherlock Holmes of rpgs, he can understand explain and counter any setup just without any of his flaws.

minor gripes some of the rpg mechanics aren't consistent, in one episode the overlord has to equip a cham to grant himself the power of flight in another he simply calls out a spell name. also for a necromancer his spell types seem all over the place and not really restricted to necromancy magic.

in my opinion the worst thing part about this show it could have been set 100% in an actual fantasy world about the last 'supreme being' waking from a slumber in his tomb finding all the other 'supreme beings' had left and be nothing todo with a guy sucked into an rpg and nothing would be lost. not to say that is a bad thing but the rpg premise is wasted.

first season was at least semi interesting you have the evil overlord type guy actually being the good guy for a change, the trapped in an rpg as an undead but my interest was lost somewhere in the second season where it seemed they weren't going anywhere with it.
