Not sure exactly what they are going to do.Personally i like the natural predators.I think having bears and wolves roaming around would be nice.Also think at night having wolves become more aggressive and hunt in packs would be pretty neat for a night threat along with whatever else.
As for dungeons/caves i'm not sure. I'm not against "monsters" but i just think it's a bit played out.
Either way,enjoying the game.Looking forward to future updates.
