2. Animal Crossing (2001)
Developer: Community Simulation
Though it's graced the Wii and our handhelds (most recently with Animal Crossing: New Leaf), Animal Crossing was most unforgettable with its GameCube debut, turning everything we knew about interior decorating, fishing, bug-catching, and being buried in debt on its head. Neighbors moved in, the town flourished, you got in some play time with retro NES games, and you learned the true meaning of angering Resetti. That's a kind of wrath you never want brought down upon you.
