I've never totally and completely given up on a hobby. I like to keep up with it now and then. I guess I grow less passionate about it, is all.
Star Wars. I had everything Star Wars as a kid. Not just the movies. Action figures, sticker albums, a Milennium Falcon spaceship, a trivia quiz machine I got at Disney, an R2-D2 cassette player, the SNES cartridges, books on SW characters and other whole books on SW spaceships... until the prequel trilogy.
Lord of the Rings. I read The Hobbit, the LOTR trilogy, Unfinished Tales. The Silmarillion. Twice. I even read some non-Middle Earth Tolkien. After the movies came out I sort of drifted away from it. Unlike SW, I liked the "new" movies, but these signalled the end of something for me, anyway.
Greek mythology. I read and re-read Robert Graves' greek myths collection, and all other kind of greek myth books and encyclopaedias. I drew my own family trees of the gods and demigods. Don't remember what the cut-off was. Maybe it was norse mythology. Or that I got a girlfriend in high school.
Pokemon. Blue, Gold, Trading Card GB games. Trading cards. Sticker albums. Board games. Watching the anime over and over. Trying to move that damn truck. I stopped following Pokemon after Gold-Silver, but I still give the GB games a go now and then, when bored.
Video games - sort of. I still buy them and I still play them and I'm still fanatical about them. I do a lot of binging and replaying and dusting off old consoles like the PS1 and PS2. I just don't play as much as I used to. It was easier in high school. Now
