Still there are tons of games for the 3DS that cost around $50 still even though it's a long time since the games were released.
No idea what currency that is. But in America, it's $40 USD. But either way, I think holding a high price is more of a Nintendo thing above anything else. I remember very early this year, NSMBDS, Mario Kart DS, and Super Mario 64 DS (a freaking launch title) still retailed new for $35. Remember, at this point we had Super Mario 3D Land and Mario Kart 7 for only $40. And yet YEARS old DS games, at least one of them eight years old, was still retailing for $35. Nintendo knows people will buy their games regardless, so they don't bring the price down unless the game sold poorly *cough*Metroid
