This game is a true standout for a number of reasons. For fans of the books, it will be a rewarding sidestory, but it is so well-written that a newcomer to Feist's world will have no problem getting engaged with it. Combat mechanics are interesting, especially the puzzle-oriented traps. Leveling up skills uses a fun system, although admittedly it can be easily abused. The moredhel chests provide riddle challenges with fun rewards. The world is huge in scale and scope, with an immense amount of ground to cover and sidequests and characters. Your missions are relatively clear and straightforward, but the game allows you to take your time completing the chapters and lets you move with a lot of freedom in the overworld.
Quibbles: Overworld graphics are somewhat lacking, but the combats are visually interesting, especially spell animations. Some of the encounters are rather difficult if you don't know what you're getting into, so save before a fight. And the sewers, mine tunnels, and kind of underground lair is ridiculously long, convoluted, and full of branching tunnels. Not always realistic, but good for a dungeon crawl :)
It bears reiteration: the world Feist has sculpted is very wonderfully delivered with a fantastic plot and well developed characters, and comes with excellent challenges, interesting puzzles, and an immersive experience.
This title is exactly what Good Old Games is all about - a classic experience that many people have never even seen, let alone heard of. Don't miss it!
