Heya,
This is taken from another topic in the Worlds of Magic forum: http://forum.wastelands-interactive....echanics/page2
All those settings are filled with wonderful ideas, anecdotes, and rich characters, and I've owned them all at one point or another and cherished them while they were in my collection. But the sad truth is, none of them (NONE) were written with the idea that people would actually need to find that information useful for actual play. Anytime you read something from AD&D, especially second edition, you - the consumer - have to go through all kinds contortions to hammer it into something remotely useful for what happens at the table. AD&D2e was an incredibly poorly written and incompetently executed game. I could offer mountains of proof, but all I need to say is this: if it were anything else other that what I have described, would TSR had needed WotC to bail them out at the end of the 90's?
