No language issues. It's pretty much hints and lore. Some strange dreams but nothing distasteful that I have noticed.

In terms of "gore" you get some blood splatter on the ground along with the drops of meat and hide. Again very light in terms of nasty factor... pig squeal might be the most shocking part of killing a boar. One food item made form intestines dropped from dead people. Not a big deal made of it, just another drop to use.

That is about it honestly... not sure if fighting scary looking monsters might be too much for your kids but I doubt you would be looking into it if you were afraid of that ha ha.

Most things get killed then "poof" in a cloud to drop drops etc... nothing really graphic there either.

On the gore / violence I would rate it pretty low end. I'd let the grandchildren play it.
