Well just like with the most disliked Fallout 4, Original Sin 2 is way too depressing, i get that story requires some drama, but i noticed that there are lots of places where it is not required yet still is.
Not going to explain why this is bad, but personaly that makes the game at least 20% worse. Seriously kids that play such games see more horrible things then some people that actually been at real war. It is a surprise that kids have not yet developed some war related syndroms.
Things you could do to solve it: remove or make an option to remove excessive gore. Remove after battle all the bodies. Remove or set optional gore loots.
Several mechanics and skills use blood and corpses to function, plus if you removed all bodies after a battle ends, you can't pick up their loot.
And even if the game were to be completely censored and the blood and gore and bodies were all removed, the whole first area of the game is a horrifying concentration camp where people are tortured into becoming mindless weapons, and it's set on an island full of the horrible tortured remnants of the victims of Braccus Rex. Should that go too?
