It's been available on Xbox 360 for a while now, and we have no word on when it will be available for PS3 users, but Hearthfire is now available on Steam for those playing Skyrim on PC.
It costs $5, and allows to buy up plots of land, build houses, get married, raise children. Just in case you were bored of all that exciting adventuring and felt like setting down.
The PS3 version, sadly, is nowhere on sight. Bethesda's Marketing chief Pete Hines said there was no information available for Hearthfire, or any other Skyrim DLC, on PS3 and it's looking increasingly likely that neither Hearthfire or Dawnguard will be made available on the console.
