IGN recently added this video of The Sims 3 gameplay, showing the Riverview neighbourhood that all buyers of the game will receive as a free download. It shows a stone-henge like area of the neighbourhood which also features in Sunset Valley close to The Goths house.
It looks like a lovely place to live. Makes me look forward to choosing that town as my town for my series. And the zooming out shows a really nice landscape. Very rural, something which I am looking for.
