I've only set up stages for practices but my goal for any stages I plan is multiple ways it can be shot. It can sometimes be difficult to do it so it's not blatantly obvious which is the best way to shot it but it frustrates some people to no end. It's fun watching the gamers come up with different plans. The flip side of setting up stages like that is the sheer volume of people asking you 'so after I shoot these guys, what do I do next?'.
