...has a really bad writing, right from the start.
I've generated a dozen of chars, and it's getting on nerves every time, tbh.
Ok, so the leader of rebellion was caught and should be executed without much noise and publicity. Tullius says how much of a piece of crap Ulfric is, and then...
...and then they both just stand aside. And some random dude takes initiative to die first, no matter that redguard woman commands the order. Goes first, says brave words, but hesitates to stand on knees...
Wait, what? Why Ulfric wasn't decapitated right after Tullius said how much of a baka he is? The whole process is about him, and there's war, and there's a full castle of rebellions who can start counter-attack to free him at any moment. Logically, Ulfric should've been executioned first, right after Tullius' words. Wth do they just stand aside and wait for something?
So, some dude was executioned first without any orders (!), but his head fills most of box, and his body prevents any next prisoner to stand on knees. WHERE does the protagonist place his knees, if there's a massive dead body right there at that moment? Where will his head go, if most of box is filled with another head already?
Also, wth all those stormcloaks in castle didn't do anything? If Ulfric dies, there'll be no more Stormcloaks, so they must prevent it at all costs, even with a suicidal attack.
Attempts to add dramatism often ruin logic. Imho, if Tullius attempted to execute Ulfric first, and Stormcloacks attacked guards, while protagonist was standing aside awaiting a desicion on his execution, and Alduin attacked all that mess, that would look great and much more logical.
Not to say again that "screw lists, he goes to the block" ruins motivation to join the Legion from the start. It constrasts so much with later game, where quest npc's are ready to fall in love with protagonist after player's tiniest effort and simplest tasks.
Also not to say that the complete lack of humour in Skyrim (Orc-Bard contract from DB and some rare dialog intros like first greet of Illusion master at Winterhold - "wait, do you see me?" - dumb dialog options for reply - aren't humour at all) isn't a dark war nordic style, isn't setting, it's just a writer's impotency.
There's absolutely no way that Beth guys didn't love the game they were creating and the world of series, but... they've put really small effort into writing, scenes and dialogs. Like, a tiny, 1-2 evenings of relaxed typing in Word for such a large and expensive game. I can't understand that at all.
UPD
How would you like to see the starting event? Please share your ideas on scenario of that Helgen part
I have a saved game as soon as I step off the wagon. I start all characters from there so I don't have to go through it everytime. It's LOOOOOOOOONNNNNNNNGGGGGGGGGGGGg
