I will be the first to say that this holds a ton of useful and usable items. It sometimes seems, however, that for every excellent item, there's a broken one. I got this for my D&D games, and it said that this would work reasonably well "with “any” fantasy role-playing game system that utilizes magic items, and manages characters with skills and attributes." And there are a good number of items which certainly work perfectly well, and I've incorperated them into my campaign I'm running. But i doubt that there are any systems out there who could function properly when you can basically buy a magic house for only 1000 gold. The cart of wonder is basically a bag of holding that functions as a normal cart that can magically seat fifty people comfortably inside. If I stripped all the walls and furinture out of my real-life house, I might be able to sit fifty people. This means that i can buy a magical moving house for less than an actual bag of holding! (The smallest can only hold 250lbs up to 30 cubic ft. and costs 2500gp.) This could perhaps be fixed with a price adjustment, maybe, but there are many other items that are game-breaking no matter how you look at it. So, there are tons of useful items, but just be perpared to have to sift through ones that could potentially turn your level ten character into a god, if you use them properly or with other items.
