Despite the fact that the work is indeed pretty much an empty shell in today's standards, we often forget that the aesthetics of IF have changed a lot along these years. In the early days, players / readers used to approach these works from a different perspective, enjoying the sensations of inhabiting and exploring space without necessarily expecting to proceed on the narrative level as we do nowadays. In this respect, Emerald Isle is a relatively fascinating construction of a virtual world with a load of hidden secrets -- though visibly inferior to those of later RPGs.
