Addams Family, Yo Bro, Ghost Manor, Shapeshifter, Camp California, Beyond Shadowgate... You can't say Icom Simulations didn't support the TG-16, now if only any of the games they made were good!
Shame, too, because I think the NES version of Shadowgate is pretty amazing, no doubt thanks in part to the great atmospheric soundtrack added by Kemco. When I first saw screenshots of Beyond Shadowgate I think in Turbo Play, I wondered why they went with the 3rd person point and click adventure style rather than the 1st person dungeon-crawler-esque style of the original. I haven't personally played it yet but it just didn't seem like it was being done right.
