Teens and college kids will always pirate, damn the consequences. However, I think with some education initiatives, you can cut down on the number of parents buying R4's for their 8 year olds.
Obviously tech savvy teens and students pirate like hell but it was seeing really young kids with R4's in their DSs from a couple of years back which seemed to indicate that it would get v widespread in the UK. Having since spoken to some parents, as soon as one kid in the playground gets it then its game over. Jonny asks mummy why he can't have hundreds of games like Timmy, whines, Jonnys mum speaks to Timmys mum who points out dodgy dave at the market sells DS games for £10 for a few dozen at a time, how can that compete with £20 up per game?!
Jonny and Timmy care only about getting lots of games at the same time as their friends, Jonny and Timmys mums care only about saving money and keeping their offspring quiet. Copyright infringement is way down their list of priorities (if at all) unfortunately.
