One game which has been under development for rather longer is Gunman Chronicles, which started out life as a Quake add-on back in the days when Daikatana was still able to raise excitement. Since then it has moved over to the Half-Life engine, and now Sierra have signed on to publish it as a full stand-alone game. It's looking better than ever, and although it's a little rough round the edges in places it looks like it could be a winner.
