Lethal Weapon 3. My first pin, picked it up for cheap in 2009 and fixed it up. Just can't get rid of it. I know its by no means a top rated game but it keeps me coming back for more. Difficulty is medium, and for some reason a good game can be hugely satisfying. That, plus the movies were great, coupled with the Three Stooges reference and ZZ Top music, I'll probably never sell it.
