The introduction to this gamebook is detailed, with technical drawings of craft and technology, and the future world of Earth 3033AD is realistically detailed. The detail of time travel is also well thought out, as there are windows which move in real time so you cannot go back to the same time twice. The story concerns your mission, as a new agent, to discover which of the Lords of Time is a renegade. There is little to go on at first so it begins a bit randomly and is a bit daunting with multiple targets and many timelines, but once you start moving it gets more obvious. That said, one of the impressive points in the book is that many of the choices are reasonable and require a good deal of thought to work out which has the best implications or even the least worst. It makes the book extremely challenging and requires more thought than Fighting fantasy used to. More like hard work but impressive.
