What are your favourite Light Novels that are at least 10 years old?
I have recently read “I Saved Too Many Girls and Caused the Apocalypse vol 1” and to my surprise it started publishing in 2011. Most novels I read are fresh, with new volumes constantly being pumped out. It drowns out discussions about stories that are older but still worth the read.
Danmachi (Is it wrong to try to pick up girls in a dungeon - blame the editor for the title, the author originally wanted one matching the story more closely) comes to mind, that series has been going on for over a decade now and, at least for me, it has been getting better and better with every volume. It’s got its problems (mostly certain characters being overly annoying) but it’s awesome nonetheless. Even now (I’ve read up to and including Volume 17) there are still questions open from the first Volume with most plot developments only deepening existing plot threads instead of opening up new ones.
Disclaimer: Danmachi is also the story that made me start reading Light Novels so my take on it is bound to be extremely biased.
