The new Sim City is receiving a rollicking from customers (USA, at east - it's not released in UK yet). Look at the rating on Amazon:
Amazon in USA has pulled the product and will not sell any more until it's fixed. It's to do with a new type of DRM - a way of trying to prevent piracy. The game needs to be connected to the internet so that you can play, yet the servers are down so very few people can play. For a £65 downloadable game, it's not good enough.
