And I will say...since this isnt an MMO and therefore how others play doesnt affect you...who cares? Like I mostly agree with Fire, but "I would rather they just dramatically raise the DC for pickpocketing from merchants, specifically. Make it high enough that if people really want to clean out the merchants, they're gonna have to spend a long time save scumming." Why do you care? If someone wants to do that...let them. It has ZERO impact on your game. From my posts, you know I don't cheese. As such, I might pickpocket a story item but I am not cleaning out a merchant. It's not fun for me, but why would I care if others did?
I care about it since it affect MY immersion. How other people are playing is not really my concern. When playing an RPG, I really enjoy RPGs that have strong in game economies. Having that element of saving up money for extended periods of time to purchase powerful items really adds to my gameplay satisfaction.
I don't like the idea of making a bunch of different merchants who only buy specific things, because although it is more realistic, it tends to be very tedious for the player in actual gameplay. "Gotta go sell my stuff, this is gonna take 20 minutes. Sigh."
I imagine not many people will agree with me here, but I like busywork in games, it adds a great deal to my immersion and makes me feel like I am "planning for a journey." Mentally planning routes between shops adds a great deal to my personal experience and makes the place feel like it actually exists to me by adding a "weight" to it. It is also why I hate fast traveling (I do not personally use it) and would prefer if games did not include it. Although by now I have accepted that games aren't going to do away with it.
