Played and completed episode 1 and it was much better than I thought it would be. The story is excellent and whilst it's basically choosing responses (with very, very basic, minimal QTEs sparsely thrown in) the choices you have to make actually do make a difference to the outcome.
The original characters and their back stories are well thought out, and you get to see Maergery Tyrell, Tyrion Lannister, Cersei Lannister and Ramsey Snow in the first episode. They've slotted the story in well to the TV series. I can see Bear's point about the lack of activity but I really enjoyed it. Just don't expect a hack n slash type affair. Tempted to get a season pass to play through the rest.
Totally disagree with that TBH. I had problems having any sort of success until I reached level 6 or 7, but by then I'd left the first area (White Orchard) due to impatience and started in the second one (Velen) which has tougher bad guys - they're also 'levelled' which is shown above them. Basically it's not a good idea to pick a fight with an enemy whose level is 2 or more ahead of yours. If you've come across someone who is way tougher, a red skull appears above them which basically means 'don't even try it - run away'.
I had a lot of these to start with so I went back to White Orchard, levelled up some more, found better weapons/armour and improved my spell strength then went back to Velen where I had much more success.
Once I got used to it, the fighting is quite good. Dodging rather than rolling away is the best way to master it, as rolling away affects your stamina. I've had some excellent battles - and as Jack says, then can gang up on you. Best thing to do is lure them out one at a time and take them on individually.
It's quite a clever system - you won't fare well if you run in all guns blazing and have to adapt your style depending on your enemy. You could also chuck bombs at them if you're able to craft them.
Only issues I've found is not drawing my sword (not really going to do much damage to a werewolf with bare hands) but that is a very rare occurrence. The camera can be a bit fiddly in combat, especially in dense forests etc. But otherwise, I really like the combat.
