That, of course, depends entirely on what your purpose is!

My purpose is to take a few relaxing moments and blow things up without working too hard and getting frustrated. My challenge is to do a better job getting through the level than I did the last time. To that end, I have favorite DOOM levels that at first seemed unplayable and now I try and get through them without taking a single damage hit.

YMMV.
