Sorry if this has already been posted but I couldn't spot it! Just noticed The Sims Medieval is now available in the store for ?3.99 here in the UK. Looks to be a Nokia exclusive as it's published by Nokia. I'm using a Lumia920 so can't confirm if it's available on other devices or not. Xbox branded so I'm assuming achievements are in.
