How much content is in this game currently?
A lot, but if you want to see it, I strongly recommend playing a warrior-thief-type character. Boost Scoutcraft, 10 is good. Get the level 15 trait that let's you wield advanced weaponry, get the saber, dagger and longbow. And when you fight, either back-stab people or shoot them from afar. One at a time.
When you master this kind of gameplay, which is what I consider the basic gameplay loop, you can play another character based on magic or one based on sex.
maybe 'Cannibal' trait as well?
Nope, only helps with honest to goodness human meats. And even then, you still need to cook them to not get sick. Oh, and human smoked meat, is really nice because is restores 32 satiety compared to the animal smoked meat's 26 but lowers Morality by 0.1 each.
Combination of Lona being weak and named characters being strong
Well, I definitely agree with Lona being weak and I respect
eccma417's vision of the game in that regard. However, I don't know if named characters are that strong, though. As an example: I remember, when doing the hostage rescue mission with Vinnie and Cecily, setting them up in a room where I would lure one spearman at a time so that they could both attack him at the same time. Even with this kind of set up, I could only bait 2 or 3 before Cecily was on the ground, out of stamina, or very low on health. I believe that the enemies' attack rate is outrageously high since every attack in this game interrupts. This is also why some of the most dangerous enemies, when not counting the wolves, in this game are the fish-kind. What with their jumping around and incredibly fast attack rate.
I would like to ask
eccma417 if this is intended.
