Overall it looks to be a WoW clone with a some different take on things such as no Horde vs Alliance but same classes and a majority of the vanilla races.
It doesn't really detract from the story the game elements are solid, it is overall a decent read.
I am not really engaged with the moments when he is out of game it mainly just revolves around his cat and minor life things.
The character has been really fleshed out despite 30 chapters, I would like to see some character depth as at the moment he doesn't have any real defining traits.
Honestly not sure what the author is building this story it reads a bit like a slice of life as the power ramping of some VR novels isn't really here that much. I guess that is probably the direction the story is going since the premise of his character is halos/buffs so he is relatively passive.
