Having a passing interest in things like video games or movies doesn’t usually mark someone as a nerd, since being one is about the passion that goes into the interest. Turning something into a hobby that you pour hours of your life into is the essence of a nerd, regardless of topic.

Of course, when we say someone is a nerd in a general sense, we usually don’t mean a movie nerd or a sports nerd. We mean the type of nerd that spends time in fantasy worlds or crafting the perfect deck for a tournament. As a proud nerd myself, these are the special interests that mark someone as such.

15 Special Interests That Define a Nerd

Dungeons & Dragons

The classic tabletop RPG is often the first thing people associate with nerd culture. Its reliance on imagination, rules, character sheets, and long campaigns has made it a defining hobby for deeply invested, detail-oriented players.

Magic: The Gathering

With intricate mechanics, constant expansions, and competitive play, Magic demands both strategic thinking and ongoing investment. Its mix of collecting and gameplay has made it one of the most recognizable “nerdy” hobbies for decades. Other card games have an equal amount of ‘nerd’ energy, but Magic is the most representative.

Star Wars

Cosmere

Following the Cosmere often means tracking interconnected stories, hidden details, and overarching lore. Its complexity and theory-heavy fandom make it a modern example of deeply engaged, knowledge-driven interest.

Harry Potter

While widely popular, dedicated fans often engage deeply with lore, houses, and extended material. That level of continued involvement places it firmly within recognizable fandom and “nerd” culture spaces.

Comic Books

Keeping up with comic continuity often involves decades of storylines, reboots, and alternate universes. That complexity, combined with collecting, has long made comics a core pillar of nerd identity. Following the Spider-Man movies won’t make you a nerd, but following the comics will.

Manga

For western audiences, manga is just as nerdy—or even more so—than comic books, since they are read “backwards.” Anime is becoming more and more popular, to the point where few are considered nerds just from watching anime, but the same is not true for following manga.

League of Legends
