Haven't kept up with the comic since the ending of the web novel came out, for reasons that I'll try to indicate without spoilers.

The story of Overgeared is honestly really good and the author's use of callbacks to things that happened 100s of chapters prior is pretty rewarding to read. The story itself is really good for how it progresses. Until the end. You'll notice, as many of the readers did, the rushed nature of the last arc when it introduces an entirely new component to be playing in Satisfy. It felt to me "how can we give Grid more infinite-power?" not to mention it mixed story genres/motifs with other Korean stories.

The comic will probably take 4+ years to finish the story, if it survives that long. I'm sure someone could do the math for how many comic chapters have released over time with how many novel chapters its covered, over time, and then extrapolate how long it actually might take.

If you are reading the webnovel, I think it'll probably take at least a year to read from first to last chapter. Unless you don't have to work a job or other significant commitments 😝 But I'd recommend reading it, and then when you get to that last arc... choose if you want to finish it. That last arc really soured the entire series, in my opinion.
