Yes, they are extremely useful--I'd say most things can apply to a lot of fps-type games. And if there's anyone that doesn't believe me, let Badger take you out to a "certain" GR map <giggle>, and you'll be walked through many of the SOP lessons first-hand. Every time you die it will be because of a mistake you made that was covered in the SOP's..... I'll never forget S,S,S,M

.
Although those SOP's were designed primarily with GR in mind, much of it can easily be incorporated into JO. When you read them, much of it will strike you as being simple, and common sense, which it is, and yet so many ppl make those very mistakes....
