passenger system perhaps. i coulda lived with that tho.

im more refering to the lack of original courses that stood out. i've beat every level on both mk64 and DD, and 64's stand out a lot more in my memory.
Many of the tracks were too short, and lacked a real sense of design and short cuts.

Then they totally destroyed battle mode. maps are so small you can barly move around in em, then they give you weapons that litteratly take up the ENTIRE screen in size. mk64 had huge battle maps in comparison.

weapons dissapointed me also. and the look of the go karts, i prefer go karts, like that pic above for the japense arcade game rather then Mario Soap box Durby cars in DD.
