So, yesterday I finished my first playthrough with my third character (Melee/Dodge/Subterfuge/Mechanics,Biology,Tailor) and sofar found the game to be really enjoyable (honestly can't wait for the full version). The few minor gripes I had have mostly been mentioned in other threads (like
here), with one exception:
Pickpocketing right now is completely useless.
Even though my character has taken all feats relating to stealth and pickpocketing and sports decent agility ( 6 ) and fairly high dexterity ( 8 ), I was unable to picka single person's pockets.
In most cases, even with the halved duration/higher movement speed from the feats, maxed skills for level 7 and a hefty stealth bonus from items, in most cases NPCs switch to alert when I'm not even halfway done with initiating the steal attempt. From my sporadic tries (granted, I didn't try everyone, especially not nameless NPCs) most characters had nothing to steal anyway. But after I got the vault key card to Gorsky and couldn't convince him to fork it over, I tried stealing it. I could catch a glimpse of it in his inventory, indicating stealing the card is indeed intended as an alternative to persuading him, but no matter what direction I sneak up on him from, I can't get it back because he gets alert the moment the pickpocket interface opens up. Especially annoying since at character creation I literally had to choose between persuasion and pickpocketing as my final skill.
So tl;dr: Pickpocketing badly needs some finetuning. As it is, it's not worth the skill points, especially not over stuff like persuasion.
My suggestion would probably be to solve it like in Fallout, where being in stealth mode was not required to pickpocket someone. If one considers realworld pickpockets, not all of them succeed by not being seen, but instead appearing inconspicious.
Or, if that would be too much effort this far into the engine design, provide alternatives in dialogue utilizing the skill for things like key cards, quest-related objects or similar your character
knows the mark carries on their person. As in
"[Pickpocket] Distract Gorsky with some questions about the training consoles while trying to filch the vault key card."
Other than that, I now started with a fourth character, whom I explicitly built to be able to get into the burrower caves, so, comments on those are pending
