You're talking to the wrong person here, as I often commented my choices but got nothing back, or even got a a few snarky remarks/reactions in return lol.
Reading is easy to me, not so much than watching anime. I completed about 14 or so the last handful years. Real life? Plenty of that to the extent that I rarely have any other hobbies than reading, clubbing from time to time, and sports. I'm tame in comparison to others and quite the opposite from a couch potato. :)
PS: 100 chapters are not a big challenge if you're used to reading. It also depends on the amount of text, obviously. Something like Beck, Baki Series, or most of Tsutomo's works for instance are quite literally page turners, and I daresay that you can easily finish 30+ volumes in 8-10 or so hours without having to neglect the illustrations. If you want to. Bakuman, Nausicaä, or Cromartie take a bit more effort due to them being dialog heavy.
Where's your creativity, cmon! At least say which one you liked best or something.
Also, how do you manage to read such a vast amount of manga? It can easily take a month for me to finish a 100 chapter manga due to real life stuff.
EDIT @crescensXG I see, thanks for the reply! I've tried to get into Rumiko Takahashi's work but it's all sooooo artificially drawn out lol.
I'll check those recommendations out, I've been meaning to read Nausicaä for a while now.
Usually I try to shake things up a bit from the usual 1 word answers that are prevalent in the Forum Games, it's more fun that way
