First it offers compatibility with XFO. If you use the XFO barter tweaks you the mods you order now are effected as well.
Second it's not that all barter tweaks make everything ridiculously expensive.
I don't use XFO barter tweaks, I don't know what mod has added it without my knowledge,
(which I don't like) but I've noticed stimpaks jumped from 47 caps to 104 caps each.
I care as much about the economy of a game as much as I care about the Lore.... ZERO,
there's some thing in NWN and NWN2 that after all this time I still can't afford,
same goes with Dragon Age.
OK, was just curious, I don't have the time to scrounge around for every single bottle cap in the game,
to buy stuff, most of what my character has is looted, stolen or a quest gift.
I rarely buy things in a game.
I'm not going to turn a game into a job
