I never played city folk with other people I was like 9. It will always be my favorite gamee not only from the animal crossing series but every game in the world.
Though I still like the game compared to Wild World (Though the villager conversations in CF are terrible compared to WW) when it comes to how many features are in the game.
I've pretty much abandoned Animal Crossing: City Folk as a whole since the day I got the Japanese version of Animal Crossing: New Leaf back in late 2012, even though it still had online. For some reason, I spent well over 1600 hours on this carbon-copy of Animal Crossing: Wild World released on the wrong system. Right now, it's totally not worth for me to waste time on it unless I'm incredibly desperate for some more Animal Crossing fix.
I try to play it once a week or once every other week. With AC:NL, Fantasy Life and the new Pokemon out I've only been playing a little bit on the weekends to catch bugs and fish, work on my catalog and try to finish my houses.
