Yes, numerous of the adventures, especially the one in Godsbreath and my favorite adventure, the Fiend in Hollow Mine, are very fun, memorable adventures. Radiant Citadel is written in such a way that its many good adventures give you both new angles and new storytelling paradigms in very unique settings that are fleshed out enough so as to be appealing to explore and elaborate on. Trail of Destruction is another great adventure in there with many cinematic moments and arenas for its combat, and very fun NPCs that I personally love. On top of that, Radiant Citadel feels like it was made for modern tables, and that's because it was; every writer on the team was not an old-hat WotC personal, but an international freelancer of this generation of game design.You can probably take your foot off the gas a little. The very post you quoted was me acknowledging it was an oversight. I realize we are on the internet but that doesn't mean it has to be ALL CAPS RAGE all the time.
Try making an actual case for Radiant Citadel if you think it fulfills my desire. What is good about the adventures? How is it better than the shallow, disjointed adventures of Candlekeep? Are there any real standout people will be talking about in 20 years like Sunless Citadel?
To me, Sunless Citadel isn't' that interesting, and I haven't been able to get a group to run it. It is a good adventure, but it isn't one that a lot of newer generation tables are super looking for. Radiant Citadel is, and it does it in spades. The gazetteers are all amazing too. The settings are fresh, evocative, and inviting in a way 1st party settings generally aren't.
