There may be no monsters to slay or racing cars to spin, but new video games that claim to stimulate the brain or translate languages are being snapped up by a new crowd of gamers.

The people snapping up these games often have never touched a console before -- which is both a surprise and welcome news for the industry, suffering from a decline in the market.

Nintendo Co.'s program, "No wo Kitaeru Otonano DS Training" ("Brain Training for Grownups"), for the Nintendo DS portable console, has proved to be a blockbuster hit, selling more than 1.5 million units since its release last May.
