I think that it will be interesting to add to the game a lock picking mechanic with the possibility to craft tools to do it.
If you play like a thief you have today two ways to rob an house :
- Hope that a player have an open chest near a window.
- Use explosive to open a wall or door.
I know that add a lock picking system need some reflexion for game equilbre. Maybe it could have % chance of success based on survival skill and depend from T1 / T2 or T3. The animation should be have many significatives seconds to do it. A open door could closed after 1 minute.
