Back in Wild World, my best friend was definetely Joey, he was the first villager I introduced myself to and I loved how he was always talking about food.. But Rod and Pecan are definetely up there as well!
In City Folk, Simon was easily my best friend.. He was the only one of my original villagers I considered keeping forever.. I'd never had a monkey before 'cos I never unlocked them in WW, and he was just so sweet
In New Leaf, it's easily Sydney, she's quickly become my favourite villager of all time, pushing Joey back slightly, but she's so epic, and she's always so nice to everyone.. Plus she's purple, what more needs to be said
