Smash Bros. stages are much more dynamic than the stages in other fighting games. Most stages feature hazards that will have a big effect on the match. The Wii U version features more stages based on home console games than the 3DS version.
This new game features a mix of old and new stages. Press Y before picking a stage to edit its soundtrack. Pressing X before selecting a stage will take you to the "Omega" version of that stage. Omega stages basically turn every stage into an alternate skin for Final Destination, which is great if you enjoy playing on Final Destination a lot but get tired of the same background and music every time.
