I guess I just like a lot of the shows and games. The Japanese live action department is horrid(Hong-Kong action flicks FTW), but the animation is just something that always comes up relevant to my interests. The animes are usually nothing new, but some really strike a chord in me. Serial Experiments Lain had me thinking about it for days. I don't feel validated by any work of Fiction. I feel validated by whatever I learn from it. Even if all I learned was that ponytails are sexy. I still have my own impression so I'm still alright, or something.
Also, the history and mythology is fun to read about when I'm on a wiki-binge. That and WW2. Also read about terrorists groups in Japan.
The games? JRPG formula is pretty fun. After playing so many of them it's just become a habit to pick the latest one up. It's not like they're more expensive than any other game on the shelf. All games are pretty unoriginal these days.
As for import? Japanese games are the ones I almost always pirate. There I said it!
My wallet is my best buddy and the import price is usually obscenely high. Sometimes I get whatever the local hobby shop can get their mitts on.
I often get chewed out for not wanting to actively learn the language and go live there. I'm told that I'm not respecting the culture. I honestly do NOT care though. Moving to Japan would be financial and social suicide. Learning Japanese intensively would be a wasted skill in this case. Python is far more interesting. *shot*
I respect the culture by keeping to myself and not floundering about in a Xenophobic economy that requires you to be alert all the freaking time.
The music? Heh, well it's catchy. Just like the overpriced dogshit that plays on American radios. So long as you're aware that's it's carries no value beyond the superficial barrier then enjoy it all you like. By all means don't buy it though! I also has some Korean pop as well. Again, lyrics amount to dogshit, but the synth is addictive.
