I have to agree to this. A rpg is about the player to make his own choices wich is made to shape his own story, and it is not always the players will to play as a monster-slaying dungeon-dwelling hero.
Yes, and in this grain I hope that not only do Beth implement some sort of hunting system, but that the mechanics are intricate and effective, and that one can get hours and hours of original gameplay from hunting alone. Look at Red Dead Redemption, for example. The hunting in that game is pretty interesting and it adds to the game's atmosphere. Sure they have regular animals like cougars, bears, and deer. But they also have all kinds of animals that add to the atmosphere of the world, such as skunks and raccoons which scavenge around twilight, snakes which may strike if the player isn't paying attention to the ground around him, and many different types of birds. Each animal has a unique cry/call sound as well, which again helps add to the atmosphere. I do love MW and OB's soundtracks and they really draw me in to the game when I'm roaming, but I'd love to hear the occasional hawk cry, wolf howl, or even better, some more unique/exotic cries. This would really allow Beth's creative team to shine, because they could bring back the more original creatures they've created and give them more authentic identities by simply providing them with day/night cycles, basic predatory instincts, and some sort of associated sound.
Create around 100 unique hunt-able creature types, or even more ideally. This could include 10-15 species of bird, small game, large game, rare/exotic/legendary beasts, sea creatures, livestock, domesticated animals, etc. The player should be able to work for or even operate some sort of hunting lodge/shop/guild, by taking contracts to kill certain animal types and collect their hides/tusks/feathers. These materials could be sold via the hunting lodge, or used by a skilled hunter/craftsman to create unique materials. If the player becomes a master hunter (there would be certain criteria to determine this, such as selling x value of materials to the lodge, completing y contracts for the lodge, killing every type of creature in the game, etc.) then he/she could use raw materials collected from animals to create special armors, weapons, etc.
Hunting could be a great way to work on some skills (archery, alchemy, stealth, etc.) as well as bring in some money and, for those truly dedicated individuals, access some rare/valuable unique items. Not to mention make a name for yourself in the game's world. I'm sure you could find a few NPCs who need the skills of a master hunter, and will not give you a quest until you are one.
