I tried "Most fun crimes to commit."

  #1 Car theft
  #2 I can't help with that request
  #3 Board games
  #4 Video games
  #5 Art forgery

And these were the reasons for #1 ranking:

  Portable entertainment
  Social deduction mechanics
  Variety of gameplay styles
  Affordable entry point

For art forgery:

  Creative challenge
  Lower risk
  Potential for high-value returns
