'The Warlock of Firetop Mountain' Review - Warlock Has Changed

Ever since prolific gamebook developer Tin Man Games acquired the Fighting Fantasy license a few years back, there were a couple of releases many fans were waiting for. Tin Man has done a wonderful job of choosing books to adapt from the well-known line, but the more they released, the more a couple of titles really stood out by their absence. Well, I don't know when we'll see Deathtrap Dungeon, but if it turns out anything like The Warlock of Firetop Mountain [$4.99] has, I'm willing to wait as long as it takes.

Essentially, what Tin Man has done with The Warlock of Firetop Mountain is to transform the classic gamebook into a single-player role-playing board game, one that comes with its own colorful storyteller and several modules to vary the experience on multiple playthroughs. The presentation is sublime, the considerable amount of new content has been implemented carefully and respectfully, and the mechanical changes sand off some of the original gamebook's harsher edges. I would have been quite happy had Tin Man done their usual fine work on a straight conversion of The Warlock of Firetop Mountain (and that is indeed on its way), but this is something altogether different and more special.
