The fantastic website, Good Old Gamers (GOG), has put out Ultima IV for free today. I'm not certain whether it will stay free forever or if it just for today, but nevertheless there is no reason not to download one of the great old Ultima games for free! I've never played this Ultima, but it looks like a good old top down rpg that is probably quite difficult and full of rudimentary mechanics and commands. Head on over to GOG and check it out.
