I have a friend who bought a Wii and a DS with the sole intention of cracking them for homebrewing and to pirate games which he would hire from Lovefilm and copy.
After about a couple of weeks he just gave up, because there weren't even enough appealing games for him to pirate, and now his Nintendo consoles just collect dust.
I think that's the real problem, there aren't enough decent Nintendo games in Europe, not that people are pirating them.
I've been gaming since 1983 and have never even played a Nintendo game for more than 5 minutes, and have never owned one of their consoles.
Their games just don't appeal to me, not even when I was a child, I had a much better collection of Amiga games, and most of my gaming chums either had an Amiga, an Atari ST or if they had a console, it was either a Megadrive of Mastersystem. Throughout my gaming childhood, I've only known 2 or 3 people with a Nintendo.
Also, like my privateering friend, if I was a pirate, I couldn't be bothered to pirate a Nintendo game, let alone buy one.
