What Mario game would make a good stage?
Donkey Kong
Mario Bros.
Super Mario Bros (Mushroom Kingdom/Smash and Melee)
Super Mario Bros: the Lost Levels
Super Mario Bros 2 (Mushrroom Kingsom 2 (subcon)/Melee)
Super Mario Bros 3
Super Mario Land
Super Mario World (Yoshi's Island/Melee )
Super Mario World 2: Yoshis Island (Yoshi´s Island/Brawl)
Super Mario Land 2
Super Mario RPG
Super Mario 64 (Peach Castle/ smash and Melee, Rainbow curse/Melee)
Paper Mario
Super Mario Sunshine (Delfino Plaza/ Brawl)
Paper Mario 2: The Thousand Years Door
New Super Mario Bros
Super Paper Mario
Super Mario Galaxy
Spinoff Series (kart, golf, tennis. . .) (Mario Circuit /Brawl)
I can think of a retro stage:
The perfect Mario 3 Stage:
Like Big Blue in Melee but slower
And a Paper Mario Stage:
Let me know if i miss any game/stage.
