Games like Skyrim have roots in Ultima VII, and without this monumental testament to existing in a virtual world, very few of the titles with their updated graphics even comes close to the wit, charm, and intense experience that is Ultima VII. I actually learned more from this game that I did from most of my formal education. The storyline (especially part 1) is so involving and entertaining you probably will shut yourself away to live it out if you let it hook you. Be warned :)
