Gamers are intimately familiar with the beta stage of game development, especially in a day and age when many companies are currently bringing those players into the process. Preceding that, though, is the alpha stage, which most players of a game will never see.
With Mario & Luigi: Dream Team, though, Nintendo has instituted what they’ve deem the gamma stage, a third major build in the development process. This is a direct product of the 3DS’ hardware environment, which presents the added challenge of producing visuals that hold up in stereoscopic 3D, even when they mix polygonal and sprite-based elements.
As such, the game has been in the works since Bowser’s Inside Story was finished back in 2009. It will be out on the 3DS on August 11.
