There hasn't been a "I've figured out" thread in a while. I hope they're not banned, if so I apologize.
We all know RolStoppable's life revolves around the Wii and DS but why doesn't he like Animal Crossing? I've come to believe that it's because contradicts his lifestyle. RolStoppable has a primarily sedentary lifestyle that can be summed up by VGChartz visits, Wii and DS playtime and roaming in his parents' basement. Animal Crossing on the other hand, emphasizes going outside and embracing what your village/hometown has to offer. I fear that playing Animal Crossing might remind him of what life has to offer and that there's a world outside the walls of his lonely basement.
It makes perfect sense.
