Well… it is a Baldur’s Gate game (as much as I’ve seen claimed otherwise), so the story is centered around the usurper gods of death, their legacy and their attempts to gain power and influence in the world.

The first act is reasonably light (with exception of mindflayers and some light occular body horror :P), just normal dnd stuff, goblins, druids, etc.

The second… well, to avoid spoiling too much, let’s just say it goes dark. :P Haven’t seen the third yet, personally.
