Ok first off, I'm going to play abit here, so don't take anything I say too serious.
Perhaps for you it wont ruin balance however for everyone else it pretty much trivialises making money, why rob houses or explore dungeons for phat loot when you can just easily teleport between towns buying and selling goods?
Because it's an RPG, if you're a thief in real life, hopping around the world with "magic" to trade goods that you buy is silly.
Any RPG'er that does so is not really a roleplayer and should seek other games to play, like CoD ( man I love gamers tudes to things ).
Now being a traveling merchant would be a cool idea in a game that diddnt have fast travel and the player had to take the long walk between towns fighting off bandits who seek to make your goods their own
Not good great.
but the fast travel mechanic bypasses all of this and pretty much svcks the fun out of the idea turning it into little more than a cheap exploit.
My fault, I never should've posted in the first place.
Now you can use the argument "if you dont like it dont use it" however it doesnt work that way, you might as well place 1,000,000 septims or the most powerful armour and weapon in the player's starting cell and say "here you go, please feel free to exploit these septims and powerful items by having them right from the start of the game, however if you earn these items properly then you dont have to take them here".
I'm a PC, I can and so can most TeS gamers do this at a drop of mouse button.
Does that make the CS an exploit that needs to be closed.
I've added 10000000+ caps via Console commands at the start, you know what it got me, nada, zip, zilch, as most stuff is leveled in lists.
I can't buy a house that I could not get with one cave delve, as most are again leveled to fame.
Most weapons are awful, you can reliably find better with one fight.
I've added uber gear, and am happy to do so, however due to the RPG'er in me it's not very uber.
It's not rare just a unique garb to suit exactly the role I designed and put effort into creating.
That and if you cheat in uber gear, it'll cost you more unless you also hack your stats to allow for maintenance.
So in effect you have to cheat, you have to chose to cheat, you are cheating;
Not using a glitch that is an unavoidable part of making a certain roleplaying ability available to all.
Now dont get me wrong I like the idea making a bit of coin trading goods between towns however it simply doesnt work in a game with fast travel.
Nope it works fine.
However it does not work in a game with cheating baskets that need their hands slapped and told by their mummies to play nice or it'll get taken away.
