I see TW3 continues with only two dialogue options. Ffs even mass effect 2 had more options on a fucking dialogue wheel
TW is mostly about C&C rather than dialogue trees. Since characters are literally set characters from books so it's not like you could make out of Geralt mass murderer in Fallout esque way without braking his character and because those C&Cs don't resolve after choice it creates some sort of web that is different to other RPGs.
Take for example recent game Pillars of Eternity and first "dungeon".
You have binary choice: Stay and rest or move out.
If you choose A - after rest you loose companion.
If you choose B - you don't loose companion but other companion is worse because of it.
If you would aplly same choice but with TW1 system:
If you choose A - you rest and near the end of dungeon you lose companion (i am fed up with you i will go alone !)
If you choose B - other companion after a while will get severe health problem.
Each of those choices are esentially the same but only TW1 style choices make you stick to your choise since you can't simply reload and pick different choice.
As i heard from few interviews developers agreed that TW2 C&C focused to much on background rather than on foreground thus loosing part of what made TW1 C&C system so good and in many reviews made remarks that they will try to do like in TW1 C&C where consequence part of choice will come much later.
