Just a heads up... you can get some good armour and weapons before you leave the starting zone, I levelled to 3 and had a decent set of armour and a good shield and sword, staffs drop as well.
Graphics cannot compare to Witcher 3 because they've been designed to accommodate 100s of players at once in any given area... the player models are hit and miss, some races are better looking then others, I like the redguard race. This being said, the buildings look this gen, or very good last gen, but some graphic elements do look dated, the water springs to mind.
There is lag as it's just released, but this will get sorted I'm sure.
Really enjoying it... quest markers are confusing at first but you do get used to them.
8/10 so far.
