#Instead of the hub world of the last game, Galaxy 2 will include a map system similar to those in Super Mario Bros. 3, Super Mario World, and New Super Mario Bros. Wii.
#This is navigated via a mobile planet called Starship Mario (so named because it's shaped like Mario's head), which can be visited anytime and is expanded upon when new abilities are unlocked.
#Completing levels unlocks new stages, but certain areas cannot be accessed until the player has collected a certain number of Power Stars. Players can also collect #Comet Medals hidden in the stages to unlock harder levels with tougher challenges.
#Similar to New Super Mario Bros. Wii's 'Super Guide' feature, Galaxy 2 has a 'Cosmic Guide' feature that lets the computer play through a section of a level if players are having difficulty. However, if players use this, they will only receive a Bronze Star upon completion, requiring them to complete it themselves in order to earn a Power Star.
#There are also monitors that show hints to the player.
#As in Super Mario Galaxy, Luigi is also a playable character, unlocked whenever Mario can locate him at the start of a level.
#Clearing levels with Luigi unlocks a Ghost Luigi representing a developer speed run that players can race against for completion time.
#The game is also said to have 240 stars according to Miyamoto so with 240 stars all up, with you needing to get all 120 GREEN ( so 120 yellow, 120 green all up) Stars to access last Galaxy
