Been waiting for this quite a long time...and I'm glad to report the wait was worth it. I was happily surprised by a rules-light system that works, and promotes role-playing and thinking. Lone Wolf was never about dungeon crawling and monster killing, but stealth, smarts, overcoming riddles and social situations, and I was glad to see the whole mood/theme, but also spirit, of the gamebooks remains intact.
Really, a perfect introductory RPG for everyone, hopefully one that will gently push new players towards thinking over problems, playing in-character and heroically rather than killing things and taking their stuff.
There are a couple of negative points here too, like the art, which is great, but not as great as Chalk's from the original gamebooks (true, few things are). Also, it could be seen as too simple by some. But so was D&D in its basic book. There are few rules here, but a lot of smart ways of implementing them, and making rules/choices on the fly.
I know it sounds weird, but as someone who has tried almost every system around, I curiously find this to be my game of choice from now on. I grew up with Magnamund, and I am very pleased from what I see here. Simple, yes, but in the hands of an experienced GM, I believe the system can shine. It could be one of the effects of getting old, but I prefer simple, rules-light systems these days, and this is too to-the-point for it not to be perfect for my tastes.
If you grew up with Magnamund and the adventures of Silent Wolf, go for it. It will take you back. :)
