Someone on here posted an answer that was in favour of the PC game 'Uplink'. I went to the site www.uplink.co.uk and downloaded the free demo. I know that gaming is a personal preference thing but I can't express enough how good this game is in terms of accessibility and atmosphere. I've ordered the full version and thought maybe others may like to check it out.
its quite cool when you order it, as soon as you submit your order, not only do you get the copy sent to you in the post you also get to download the full version straight away!
