Tribunal was a masterpiece of bad design. I hate to say that, because at the time it was easily my favourite part of the game, but it was clearly rushed out to capitalise on Morrowind's unexpected success with little concern for balance, consistency or, for a large part, quality. The player is railroaded into performing the most idiotic tasks with nary a peep of protest; sure, an RPG staple, but ashstorms over Mournhold? Really? The Dark Brotherhood plotline that gets you into the expansion in the first place just drops off the narrative radar without any real conclusion at all, sending you into the "Main Quest" - a bunch of loosely-tied-together fetch quests for Almalexia with nothing tying them together and no motivation for the player except "well, uh, we were married in a previous life, lol", and I'm not sure what killing liches has to do with that. The hidden tongue, the murder of the previous ruler, Barenziah's general existence... hell, what wasn't dropped off the radar a few quests in? Doing dumb fetch quests for a ginger bint in a bikini? The difficulty is all over the place, with random thugs in the sewers insta-killing your Nerevarine, evil peasants turning out to have superpowers, fucking Gaenor, your average goblin mook doing more damage than any other enemy in the game and carrying a lumpy wooden sword on a par with Daedric weapons; if I recall correctly, the goblin swords did up to 70 damage! The dual paths of Helseth and Almalexia end up not being used at all after the first few quests, and are buggy as hell when they are. Helseth's presence was the perfect opportunity to offer an alternative to the dumbfuck Almalexia questline, or at least a handwave of "I think she's definitely up to something, play a long until you get the opportunity to discover her long game". That's literally all he had to say. But he doesn't.
It's rare these days that railroaded narrative is enough to wrest my enjoyment out of a game, but hell if Tribunal didn't manage it on a recent replay.
