What have Star Wars, the Apple iPhone and Brain Training for the Nintendo DS got in common?
They all buck the rule that sequels suck. Star Wars 2 (or 5 if you're counting George Lucas style) - "The Empire Strikes Back" was arguably the best of the Star Wars movies, while the Apple iPhone v2 has yet to be formally announced but you can bet your last cotton-pickin' dollar that it's going to be vastly better featured than the original.
And now we have More Brain Training on the Nintendo DS and it's not just better than the original, it's light years better. To have gone from average to outstanding in one version jump is very impressive. Maybe they should have called it 'Much Much More Brain Training'?
