Disclaimer: I have followed the updates closely, but I haven't been too active in the board, yet, so I hope this hasn't been discussed, yet.
I am just playing IWD2 CE again, and one thing I find really annoying is the way merchants work(ed) in IE games, i.e. you have some person standing around somewhere without protection, but carrying items worth 10 billion gold. BUT she doesn't need protection, because killing her will maike all the items magically disappear, as well.
This makes for bad roleplaying in my eyes. If a merchant has 50 armors for sale, she should have them in (possibly locked) chests, instead of on her (or does she have STR 50?). She should also be able to protect them herself, or have guards or be in a town that has law enforcement. Should she not be able to defend them, then you should be able to rob her items, anything else just doesn't make any sense. IIRC Morrorwind's merchants worked this way.
Any chance PoE will have good trading mechanics? How is this planned in PoE?
