Stages are one of the unique features of Smash Bros., with each stage having unique layouts and different elements that spice up play. A major difference between the 3DS version and the Wii U version is the stages. The stages in Super Smash Bros. for Nintendo 3DS are mainly based on handheld games, although it does share some stages with Super Smash Bros. for Wii U. To be a good smasher, one must know the ins and outs of every stage, and be able to adapt to the unique challenges presented by each.
Omega Mode
New in Super Smash Bros. for Nintendo 3DS and Wii U is the Omega Mode feature available for every stage. By pressing 
on the stage selection screen and choosing a stage, you can play on the Omega form of said stage, which is a single, flat platform like that of Final Destination, with its size adjusted to that of Final Destination as well. These stages are not playable in For Fun, but is the only type of stage selectable in For Glory.
