Well, spoilers in light novels related to gamers can be really annoying. For example, if you're into a game - based light novel series and someone reveals a major plot twist about a character's in - game power - up or a crucial event in the game world that the characters are part of. It can ruin the excitement of discovery when you finally get to that part of the novel.

Yes, gamers can be affected by spoilers in light novels. If a light novel is based on a game they love, learning key plot points in advance can take away the joy of experiencing the story as it unfolds in the book.
