This isn’t the strangest news ever, but usually when you think about a Nintendo 3DS game, you think about 3D; probably the biggest thing about the new system.  Nintendo’s latest eShop title, Fluidity: Spin Cycle will not be available in 3D, but if you’ve seen any gameplay on this title, you should know why.  The reason this game is only playable in 2D is because it’s a motion-based game that requires you to tilt your system side to side to control the environment, which moves the water on the screen (you).  It’s nice to see games relying on other features rather than 3D.
