I never understood why consoles and handhelds went from cardridges to CDs / DVDs and typical Flash memory. There wasn't by far such a big problem back in the NES / SNES days, as it was just hard as shit to copy games onto such a cardridge. Then they switch to a medium everybody and their mom can write to, and all of a sudden are surprised their games get copied. Don't cry that someone comes into your door if you leave the key under your doormat.
