The Pokemon Black and White 2 case is a bit different. This is not a brand new game, this is the second iteration of Pokemon Black and White. While Nintendo has evolved and has made it a lot more than a third version, it is still the same game.
Same engine, same world, same Pokemon. This is the same Pokemon generation. It is between the third version and between the real new generation.
When Pokemon Black and White came out, it was universally acclaimed as the ultimate version of Pokemon and the game was so superior compary to the previous one that it got very good ratings. For me it is simply the best game on the DS, easily.
I did not play New Super Mario Bros 2, but judging by what has been said and wrote by Nintendo, players and reviewers, it is not an ambitious game. Not a mainline Mario. It was ordered quickly to boost 3DS sales witht he new model. It was not developped by the main team, which is currently working on New Super Mario Bros Wii U, which is the main game and will be far superior to NSMB2.
When I see the horrors that RE6 have become and FF lost istelf in endless cutscenes, we can only grant Nintendo fullthanks for keeping the quality of their series intact.
