For a lot of people, the Elder Scrolls III: Tribunal was a bit of a let down. Things just didn't play out as epicly as there was potential for. One man, Antares, has gone above and beyond to remedy the issue, having created a complete overhaul of the Tribunal questline. You can nab this mod here. I haven't tried it myself yet, but I've been following it's development since Antares first had the idea. It promises to be a fantastic experience.
Need more encouragement? How about a chance to talk with Sotha Sil in the flesh, and a chance to fight Mehrunes Dagon?! Let me know how you like the mod in the comments, I'm interested in everyone's take on it.
For anyone wondering, by the way, a fairly major overhaul of the guide is underway, kind of hinging on whenever Hrnchamd gets around to implementing 3D water waves in MGE XE. You also have a Fallout 3 modding guide to look forward to in the near future, currently being written by my good friend Lusit, as well as general tech/gaming related news posts out of him!
