I thoroughly enjoy both the lockpicking and hacking minigames and was thrilled to see them make a return. In my opinion, the structures both minigames are a good fit for the Fallout universe.
I also enjoy the fact that they give me free exp. It makes me sad when I inadvertently pick up a key or password (neither of which I can drop) and am robbed of the chance to figure it out on my own.
I think there are enough of us who DO enjoy them that there'd be quite a (justified) hue and cry if they were removed.
That said, I think they could be improved:
- Don't let the world stop. Simply slow it down. On Survival Mode, make everything happen in real time.
- Add in some combination locks. I'm not sure how to make a minigame out of them, but the variety would be nice.
- Make the penalty for failure stiffer. Instead of a 10 second lockout, make it a one hour lockout. On Survival, make it 24 hours. Have perks that allow the player to lower the penalties.
- Make bobbypins extremely rare and nearly prohibitively expensive. Right now, they're way too common and they only cost ~2c. Ridiculous.
- If the bobbypins are made more rare, whatever is locked up had better be worth it. In that case, no hacking for a hairbrush...
Bottom line, I'd be quite disappointed if they were simply removed.
