Wouldn't it be cool if for the next main Mario game, it would be an adventure that spanned two whole games? Kinda like the Zelda Oracle games, which are two seperate games that can be played independently. They wouldn't be half games, they'd be full-fledged adventures. However, after finishing one game, you can use the saved data on your Wii to continue onwards in the other game
The games could be, maybe, Super Mario Adventure and Super Luigi Adventure. Say you beat Super Mario Adventure first. When you start up Super Luigi Adventure, you can continue Mario's quest in Super Luigi Adventure, and maybe even acquire items that can be brought back to Super Mario Adventure. And if you beat Super Luigi Adventure first, you can continue as Luigi in Super Mario Adventure from a different perspective as well.
Also the games would be released on the same day, so that both versions would be available at the start. If Nintendo could actually pull this off, it'd be huge! And people who don't buy both right away can start with one title and pick up the other one later.
