Gameplay
There are 4 difficulties (easy, medium, hard and dark) which differ in the
skill of the monsters you face. Hitpoints remain the same.
You can bargain for more money after finishing your monster contract through
some sort of minigame.
The side quests are extremely well made with great writing and branching.
Potions are a necessity on higher difficulty levels. You only need to craft a
potion once and you can refill it if you have enough alcohol present. Potions
are upgradeable for stronger effects. Stronger potions will increase your
toxicity more
Novigrad and No Man's Land are indeed one single map, much bigger than
Skyrim. The isles of Skellige form the other big part of the game. Next to
that, there are 5-6 other separated locations, including Kaer Morhen.
No enemy respawning or at the least not very frequently
Best items in the game must be crafted
They were very impressed with the story branching and how it is not always
obvious. Correcting 'wrong' choices by saving/reloading will be very
difficult if not impossible.
Contrary to BioWare games dialogue options are not good or bad, this you will
have to figure out for yourselves.
They really liked the in-game card game Gwent, praising its design.
The game features two really big cities: Novigrad and Oxenfurt, both very
lively.
The are of No Man's Land features 25 smaller towns, some of which are the
size of Flotsam from The Witcher 2.
Geralt can rob people, although the system is too easy and feels a bit
lacking.
Journalist (level 7) was one shotted by a wyvern (level 24). No level scaling.
Ciri sequences will be (in total) 5-10h and feel more like an
action-adventure game than an RPG
Extra storage can be made by crafting saddle bags for your horse.
Many small details such as Roach stopping to eat apples from a basket
All equipped items are visible in-game on Geralt
Fist-fighting is back, this time no QTE
World never felt empty
Journalist didn't encounter any simple fetch quests
Technical
The HUD is fully customizable. Icons and quest markers on the map can also be
deactivated. Audiovisual hints (e.g. people screaming for help) will be
present if you wish to do so.
Journalist encountered no clone NPC's
Controller feels superior to keyboard+mouse.
The extremely annoying doors from The Witcher 2 are gone. Doors are now
opened automatically, no button pressing. No loading times for entering
buildings either.
Day 1 patch confirmed
Xbox One resolution will stay at 900p
Geralts beard will grow over time
Switching between controller and mouse (for menu's) is easy and fluid
Most impressive dynamic weather system in any game he has ever played
They encountered very few bugs, no crashes of freezes.
Ultra seems to have a big effect on the quality of vegetation and character
models[
No slider for LOD
Visual gore more prominent than in The Witcher 2
