A few years ago I was working on a spy-action game. One of the sub-games was a lock picking section. One of the programmers ordered a lock picking kit, along with several padlocks. This of course spread through the office like wild fire. Pretty soon there were several programmers crowding round each others desk picking locks of all kinds.
What became readily apparent was where the money went between £3 and a £25 lock.
I think I can confidently say that our lock picking sub-game was thoroughly researched.
