From wii-ware to virtual-ware and to online play over wi-fi all have a faulty design on them. Both wiiware and virtualware are limited with how much space they can have and how much it can be download such as patch to fixed some glitches or bug that are present in the game. On wifi is restriction on communication and making new friend with one another. There tons of more but I do hope nintendo fix this on 3ds and on future console.
