As I said, the corporate world is foreign to me.
I do have some specific knowledge of how shady businesses operate, unfortunately.
The pattern is consistent: set up shop in some office, fill it with classy-looking furniture. Rip some people off. Move to a new office and file a new DBA... in sum, change the company name and location without changing personnel or M.O. Their people, well-scrubbed con artists with pearly white teeth, tend to change their names a lot as well.
The fact that so many cleverer people than me are scratching their heads about this says "obfuscation, escape, cuttlefish-ink" to me. If I ran a gaming company at the center of a "pancake-storm" like the one we've conjured, I'd be playing obfuscatory games too.
Don't be surprised if NCSoft changes its name by the end of next year.
