New Super Mario Bros. 2

[TomGuycott]

Know what would be awesome? A single world map that you had to traverse, explore levels and figure out which were challenging, which were actually leading you to your goal, and making the player work for the ending rather than rolling it out on a red carpet. Even using Super Mario Land 2 as an example, which essentially just let you choose each linear world map, you were able to do ANY at your own pace, and if you got hung up on one level, you could go to a different map and try that instead.
