User Rating: 10 | New Super Mario Bros. DS
New Super Mario Bros is exactly what the name implies. It is a new take on the original Super Mario Bros released for the NES so many years ago. It takes the core game play from the original and combines them with elements from many other Super Mario Games. An example of this can be seen through the Mario butt stomp, a feature introduced in Mario64 and seamlessly integrated into the traditional 2D game play. As with the original Mario can transform from Mario to Super Mario, and then into Fire Mario. New Super Mario Bros also adds mini Mario, shrinking Mario down to fit into tight spaces and jump higher, mega Mario, increasing Mario's size the the height of the screen dealing mega damage, and turtle Mario, allowing you to sprint and tuck into your shell knocking enemies out of the way. All of these Mario types fit right into the game and allow the player to find multiple flag poles in a level helping them to skip levels throughout game.
In addition New Super Mario adds multiple mini games that utilize the tough screen. These game are simplistic yet addictive and could really have been made into a game of there own.
If you already own a DS but do not own this game leave your computer now and run to the store. If you don't currently own a DS you need to pick one up to play this game. It really is that amazing.
