NOTE: please rememebr to mark out spoilers!
here's a few I have experienced to start us off...
EDIT: part 1... i've run out of time!
Radiant AI killed my quest!
We've briefly touched on this in another thread, the idea that since NPC's can randomly interact with each other that its possible fights will start out that have nothing to do with you. This also includes character 'going for a walk' and getting killed by random wildlife.
Now on the surface this is an absolutely great concept, it certainly helps create a believable world, alas the way the 'quests' system is designed it ends up working more like a bug than a natural event. The problem is that whilst key quest characters cannot be killed many lesser quest characters can and when they die the game fails to do anything about it - if its a mision you're already on the mission gets stuck in your 'curent quests' forever, and no alternatives are offered in providing that NPC's unique info or skills. This is especially prevelant for advanced training NPCs.
SPOILER (about the main quest) : Once you have done the 'spies' mission and all the oblivion gates open you start to get assasins in all the major cities who rather than atacking you tend to just go around killing random npc's, this has so far lead to 5 seperate minor quest characters being killled in my game so far..
Rumours and General Conversation
Now with hundreds of characters I'm not honestly suprised this area of the game is far from great. I totally appreciate each character is not going to be able to hold an in depth conversation or have original information.
The issue is that whilst people will often tell you new rumors based on your own recent achievements, beyond that peoples responses and topic choices dont take into account major happenings at all.
-Your titles and ranks mean nothing.
-someone can comment on your achievements then act like theyhave never heard of you.
-'you have much to learn!' when you are higher rank than they are in a particular skill
-people that youve upset during certain quests will not talk to you even if you charm/dominate them
Quest 'Rigging'
Most of the quests are great, they allow you to use your imagination on how best to complete them. However there are a number that purposely stop you from doing certain things without any explanation. From my own experienc this includes:
-certain NPC's being able to see you no matter whether you sneaking/ 100% chameleoned etc
-certain doors are simply 'you cannot open this door' with no explanation as to why
-no taking shortcuts, as in just because youve worked out where the item is or whodunnit you are unable to complete the quest until you have done all steps their way
I realise a certain amount of this is necessary, especially in the Main quest line, but Ive experienced these in Deadric shrine quests and other lesser quests that make no difference to anything else in the long run.
----------------------------------------------------------
ok more to come, i've run out of time for now... so what do you think of the above, do you agree, how do you think they could be improved (realistically) and can you think of any other key issues with the game. oooh, and for what its worth I'm coming up to 180hours of play time so don't sit there thinking I don't love the game or anything
other planned headers : quests that overlap - no continuity / advanced trainer quests / unbalanced enchanting / NPC allys & their insano tactics / merchants / 'The guy i've just been talking to is dead' but i'm not going to panic... / etc
