I played the game today and fought a troll, and that got my mind to wandering, and I realized that a lot of the characters and enemies in the game are just one-dimensional stereotypes, with no depth or nuance.
What are Trolls? Trolls are beings obsessed with gold. Specifically gold obtained from extorting tolls from people crossing bridges. I get it. It's a "Three Billy Goats Gruff" reference. But it's a reference that's repeated over and over again (with some minor variations), as if it would be just as funny as the first time.
Even if you assist enemies, they are still single-mindedly in kill kill kill mode. Release the goblins in Luculla mine and they attack you because you are human. Heal Frederick, and he immediately attacks you for profaning a Star Stone.
Related, I find it irksome when a Source Hunter says "oh no we killed an innocent person what have we done" when the dead guys are Immaculates and I simply struck first before they did. It's silly because in this case, they're waiting for a conversation trigger during which they threaten to kill you. If you fail the speech check, a fight starts. If you pass they're friendly... but if you THEN attack the peaceful group, you do NOT get the "you killed an innocent person" thing.
