I was working for a videogame accessory company and before the launch of the 360 we were one of the few companies that were granted a license to product 3rd party accessories. The 360 used a security chip to lock out unlicensed controllers. It was absolutely imperative that we had our products on the shelf of US retailers for 360 launch day AND as a bonus beat Madcatz to launch.
So one day our CEO called me up from the US office and said "We need the
Benz Nush in China". I'd never been there before, I asked him what he wanted me to do and he just replied "Do your thing". That was it, that was all the instruction I was given.
So I get to the office in China 2 days later and in the engineering department is all this prototype Xbox 360 equipment, console wasn't even out yet and here it was and I had access to it. The 360 launch was so seat of Microsofts pants that all the technical documentation had not been fully completed and was a work in progress. I had a direct line to the accessories department head at Microsoft to report issues and for clarification. There's a lot of stuff in that documentation that I personally discovered and reported, including fixes.
It was supposed to be a two week trip and it ended up being seven weeks. I loved the place and being able to cut right to the metal with the Chinese engineers instead of dealing with timezone, emails and phone calls from the UK.
Anyway, 2 years later I'm hired to work in China as the man on the ground for one of the biggest accessory based products of all time. I already had good contacts at Microsoft so that helped a lot, Sony, Nintendo not so much they were virtually hands off in a "we'll get back to you" kind of way.
