Mr Killer here has found a brand new suit. Recently removed from the body of whomever he left dead in the next room. This is something you need to watch out for when switching genres. The players being used to needing those phat lewtz start looting dead bodies at the scene of crimes, when they should be using it as clues for evidence. Such is the pitfall of switching genres. The only thing to be done is create a situation where the extra loot simply doesn't help. Systems that aren't quite so item dependent for character power can be lifesavers in this regard. This is of course assuming that you can get your players to agree to those systems.
