Alright, I think I beat the main quest, my impression? Huge let down and made zero sense to me.
In general I must say the conversation system is the most disappointing thing in this game, I don't need to tell you all the problem but the biggest thing missing is the fact that skill based conversations are gone. Now, only your Charisma level will determine whether or not you can persuade someone. It's so bafflingly dumbed down I can't understand how Bethesda thought it was a good idea. All the past games had a great dialogue system that wasn't tilted to one character build. If you're character had high Charisma they might be able to charm their way through a conversation but sometimes Charm wasn't useful sometimes you needed Intelligence to convince someone of something or perhaps Strength to intimidate them. Additionally, if you were clever enough and paid attention you could perhaps discover or do something that would unlock additional dialogue options independent of any skills you had. In short, the past system was beautiful.
The current system is now:
A: Alright, I'll do what you said right away.
X: Sarcastic. (and then the NPC will get annoyed at which point you press A)
Y: Flux Capacitor? (General question of the thing the NPC wants, they tell you to not worry about it and then you press A)
B: Not right now/I have to think about it (NPC stops conversation and waits for you to re-initiate and press fucking A).
After thinking about it, yeah, the dialogue system is by far the most disappointing thing.
If they wanted a voiced protagonist, I'm sure they could have implemented it into the old system.
