Re: OOC: sixth form
I too consider it among my favourites, although I honestly treat Book 1 and 2 as mostly the same adventure (the Sommerswerd cicle) broken in half because of lenght.
I greatly agree with you that it's most linear, but it works in the book, because it allows it to be very action packed thanks to that. My issue with it is that the structure is lousy; there's four consecutive Harrenal entries that could have easily been condensed into one freeing space, there is the Magic Spear & Animal Kinship issue, the unbalanced nature of some combats... they don't make it a bad book, but they do reduce the enjoyment one gets out of it because of the annoyment they cause,and that's especially jarring because Flight from the Dark was just so open and free-roaming, really an example of what gamebooks should be like.
As to my favourites, it'd be likely Shadows in the Sands, by far the best Lone Wolf book in the entire series; it's just so full of energy, colour and epic, it's always a fun to play through it.
After that, my top seven would have to include Dawn of the Dragons, Master of Darkness, Dungeons of Torgar, Castle Death and the Sommerswerd cicle; they're all great for very different reasons, so it's hard to say what I prefer.
Master of Darkness, while it could have been better still, is to me a superior version of Fire on the Water, in that it features a similar very linear quest with a very gripping tone and a sense of urgency that makes it a great read, but it also has magnificent scenery, a much more powerful sense of menace and constant risk, while being much more forgiving to the player - and with a somewhat greater amount of options - than Fire on the Water was.
Dawn of the Dragon is my pick as the best of the globetrotting adventures; other books have a similar feeling, but Dawn does it better because it has a much deeper emotional connection, in that every land you travel through contains some nod to everything that happened previouslt in the series. In fact, I believe that, with some changes, Dawn would have been a much better sendoff for the series than Book 20 is, because it really is a tribute to everything that's happened before, and it brings the books to full circle by having Lone Wolf save the newfound Kai Order in the way he never was able to at the beginning of the series. Also, it was the first LW book I played, so I also have a bit of nostalgy for it which gives it even more emotional resonance for me.
Castle Death is my pick for the best "tactical, espionage, action" subset of LW books; there are many others, which I all like because the "infiltrating the enemy fortress" Lone Wolf missions are my favourites, but Castle Death as a much more exotic athmosphere and a sense of danger that the other lacks, not to mention the fact that it takes away the Sommerswerd, which always helps making Lone Wolf's challenges that much harsher, as well as the book a lot fairer overall.
As for Dungeons of Torgar, it has a very similar structure to Shadows on the Sand - it is really the only one with a breadth and an excellence in the techinal aspects (the way sections are structured, the depht of choice offered, the considerable replay value, the different routes to success) and to mix it with a story that is actually compelling and interesting to play through, which is why I like it a lot. However, it is still inferior, mostly because it is too short.
If there's one thing that makes book 5 really amazing to me is that, in its 500 sections, Dever really gets to stretch his wings and to offer both of those things (a magnificent story and a well crafter collection of divergent paths and challenging-but-not-impossible roadblocks) that makes Lone Wolf much better than most other gamebooks. It is the same reason why I think the first two books should be treated as a single adventure and are so strong an introduction to the series: Fire on the Water has the gripping story and Flight from the Dark allows an absolute freedom and a great chance of exploring; bringing boths of those things, which are the two major strenght of Lone Wolf as a series, together in the same book, is something that only Shadows on the Sand manages perfectly, hence why it is my favourite.
...well, didn't expcted that to turn into an essay, but hopefully it wasn't too boring, right? ;P
