Off-Site Reviews

>INVENTORY - Paul O'Brian writes about interactive fiction

Playing Unholy Grail puts me in mind of the old saw about the glass being half-full or half-empty. For each positive I can think of, a counterbalancing negative also comes to mind. While the prose creates sharp, clear, atmospheric images, it is also burdened with numerous grammar and spelling errors. While the game had an inventive plot, this same plot was punctuated with moments of tediousness, implausibility, and pure frustration. And while Grail is orders of magnitude better than Allen's 1996 entry Curse of Eldor, it still fails to realize both its own potential and that of its author.
