You could say I have many interests in one area. ^_^
I love videogames, manga, and anime. Because of my intense interest in the three, I choose my major just so I could learn Japanese so I could gain a greater understanding of what I'm watching, reading, and playing. I'm sure those who know multiple languages must know the pleasures of reading something of great interest in its original text! Plus I like Jpop and VGM (Videogame music).
This interest has branched out into me really enjoying the Bemani type games, such as DDR, IIDX, and Guitar Freaks. I also enjoy other games such as Pump It Up, In the Groove, and O2Jam (don't play the last one much). Before anyone asks, no, I do not play Guitar Hero. It is a different game from Guitar Freaks. Different music, different scoring system,etc. No thanks.
I also developed an interest in a board game called Go/Budduk/WieQi. One of the oldest board games created originating in China. I don't play as often as I like. I'm 9Kyu IGS for those who play. I got interested in it from the manga Hikaru no Go, a comic that deals with the game.
When it comes to videogames, I normaly enjoy playing Japanese console RPGs. Standard "save the world" variety. Predictable, but always fun for me.
I also enjoy learning about colliquial Japanese language. It always facinates me how they speak normaly versus the scripted stuff you get taught. I love the langauge. It's very literal, which as an AS, like very much. ^O^
As much as I am interested in Japan and the langauge, I will be honest and I don't care about learning about history. I'm enjoy learning stuff about modern Japan and its language, but I'm not obssessive about samurias, ninjas, eras, etc. Some people think I'm strange for having such an interest in everything else in Japan, but not the heart. I enjoy some culture stuff, but some stuff I can't get into. Period. I don't care for most Japanese movies since they are too damn depressing, but I love the more light hearted manga/anime stuff. ^_^
I used to play Magic: The Gathering and Pokemon TCCG at one point. I quit both since it was hard to find people to play after I moved away from players I used to play with. There is a community where I live now, but it's not in my interest to get back into it. I tried three months ago, but it wasn't doing anything for me. Plus it is expensive to keep current in the game, so that partly turned me off. Shame...I used to spend hours thinking of different decks to make, but money was always an issue, so I never be creative with the game. Oh well...I spend enough time with my "main" hobby...much less do I need that one.
So...those are my obsessions. ^^;; A bit long, but hard to explain in just a few sentences.
