I'll cast my lot for "Hall of the Rainbow Mage" by Necromancer Games. I am in the middle of running it right now, and it's a good solid adventure. I've only had to make a few changes to it to make it fit into my campaign.
I'm with the monkey on this. Our GM did a cracking job with Speaker, and it remains my all time favourite scenario. I think maybe because we completely screwed it up.
I guess that's the only thing I don't like about SOME prewritten adventures; they *assume* you're going to do X, Y or Z, not P or F.
Yeah I've started reading Of Sound Mind and it looks great. If Thoughts Could Kill was ok as well. Quick glances over Freeport stuff look good. There's also an adventure in an older Dungeon Coming of the Comet or something like that.
