I played Animal Crossing on the GameCube a bit - I bought a US version while over there on holiday, a long time before it came out in Europe, and the need for faffing with Freeloader tempered my enthusiasm somewhat.

I played Animal Crossing Wild World on the DS.  I played it almost daily for eight months, collecting loads of fish, bugs, even a load of paintings.  I grew flowers.  I occasionally visited after my farewell, but had no compulsion to complete anything.

I bought Animal Crossing Let's Go to the City on the Wii.  I've never played it.

I now have the 3DS game, and have so far put in 31 hours.  It's already my most played 3DS game, beating Professor Layton and the Miracle Mask by four hours. The game is a natural evolution of everything that's gone before, moving turnip sales to a shop that never closes for refurbishment, having the museum and various shops on a separate street, allowing the player to have more control over the town.  I am the mayor.

I've paid off two mortgages.  I've seen off Leonardo, a hateful leopard.  I've collected lots of fish and bugs and even some seaweed.  I've been to the island.  I've gained over a million bells.  I have a blue pansy.  I have no time to write about any of it, since I am busy playing it.  I  have posted a few screenshots to Twitter, though.
