The Elder Scrolls V: Skyrim - Hearthfire

Key features:

• Choose Your Land - Choose from property in the salt marshes of Hjaalmarch, the forests of Falkreath, or the vast tundra of The Pale. For the more ambitious landowner, purchase multiple plots and start building a real estate empire.
  
• Customize Your Home – Expand your home with a variety of room combinations including an armory, alchemy tower, kitchen, trophy room and more. Grow plants in your new greenhouse, cultivate slaughterfish in the fish hatchery, house your Arcane Enchanter in the enchanting tower, or display your latest conquest in the trophy room. Add additional features like stables, mills, smelters, gardens and more.
  
• New Objectives and Interactions – Guard your home from unwanted visitors like marauding kidnappers, armed bandits, and skeever infestations. Turn almost any follower into your personal steward to improve and protect your home. Or if you require more help, hire a personal bard or carriage driver to ease the burdens of home ownership.
  
• Adoption – Transform your house into a home with Hearthfire’s all-new adoption system. Adopt children and discover new ways to interact with your family. Play games with the kids, allow them to have pets and gain new bonuses from having a family.
