The Elder Scrolls V: Hearthfire is the second official add-on for the fifth installment in the Elder Scrolls series, Skyrim. Hearthfire focuses around purchasing land and designing, building and maintaining a homestead. The option to hire stewards, carriage drivers and a personal bard are also available. With five pre-built purchasable houses already present in Skyrim, it's now possible to own property in every hold, except Winterhold.In addition, an adoption mechanic has been introduced that allows the Dragonborn to adopt children and raise them in the newly built home, provided there is room for them. In addition, previously bought homes can be altered to have a children's bedroom fitted into them.Go to: http://store.steampowered.com/ and download STEAM client
