Like many others, the inane, childish trash-talking on XBox Live is the primary reason I don't play online so much. Like many I only play with people on my friends list -- a mix of family, "from-real-life" friends, and people I've grown to respect from forums such as this one and the roller coaster forums I participate in (not surprisingly there's a big overlap in those two geeky cultures

)
As for flying business class to and from Japan, I think you're in for a treat, Cheapy. I haven't flown business class recently, nor have I flown it on American, but a number of years ago when I was flying quite frequently on USAirways I scored an upgrade to business class on two separate trips from Pittsburgh to England. At the time US was offering a fantastic product, and it was well worth it for the spacious seat and excellent food and booze.
Even better, I had enough frequent flyer miles saved up that when I went to
Japan in 2005, I redeemed miles for a First Class ticket on ANA (a Star Alliance partner of USAirways). This was before ANA had installed the "pod seating" on all their planes, so I had "only" a lay-flat seat, but...wow. From what I've gathered modern Pacific "business class" flights are on par with that, and if so you should spend your time going over the food and drink list, stretching out, and generally living it up. The sushi I had on that flight was surprisingly good for "airline" food, for instance... The lounge access before boarding was nice, too.
