Almost 10 hours played of TB.
The game has the flaw, like The Wicher 3, of being too easy. Like, damn, how hard can be to put a very hard more that is challenging, for the veterans. And it isn't like I'm a pro Gwent player, I played casually for two months close to one year ago, and except the puzzles, I'm beating the fights by a difference of 40-70 points, playing in Hard already.
BTW, Nilfgaard in this game seems to be a really evil empire in TB. Slaving people, burning entire cities, being cocky and mocking you, etc, and it's a different tone than the one used in The Witcher 2/3, where they were presented in a bit more neutral guy, the bad guys, but more like, just another side in the war, not inherently evil.
The typical grey morality from The Witcher games is presented in hard decisions you have to take in a hard situation, and less in the characters or the setting itself. Meve is presented as very upright queen who will fight to the death the enemy, and I think it would have been interesting to remark more her flaws, she seems uncompromising to a fault, she is uptight, she doesn't seem to be able to use a more broad perspective.
For example there was a moment that seemed funny to me, in her capital she exclaims, without a pinch of irony, how Nilfgaard will stole their freedoms if they surrender. Funny, because she said that as an absolute monarch! Her normal citizens will have as much freedom under Emhyr than under her.
Although, you know, there could be a way to reconcile everything; the story you play is a tale told by the guy from the intro. So it could be an 'embellished' tale, or a biased look or hearsay, not what happened in an objective way.
