I first played Shadowgate on the NES as well, and I also miss that style of gaming. It's why I still prefer the first Resident Evil, even though so many of the sequels are incredible- there's an atmosphere and mystery to the mansion that hardens back to those point-and-click adventures I loved.
Looking forward to your Uninvited review!
