Beyond Zork is an interesting entry for a few reasons. It's the first Zork game not derived from the original larger Dungeon game, and it was made after Infocom made an ill fated venture into business software. And it tries several new things as the technology evolved - instead of just being a text adventure it incorporates RPG statistics and combat elements, along with a crude on-screen map. It both is and is not more Zork, but it's worth checking out at least.
