There may be an obvious place for this, but I am not sure how to keep score when playing X-Wing. Looking at games on YouTube, say Gold Squadron, for example, they will overlay points during matches so when time runs out they can say who was ahead and declare a winner. I can see on the Squad Builder PDFs that it lists a half-life and point value, but I wasn't sure how to keep score based on that data if you were wanting keep matches to 75 minutes to allow for more games in an evening.
Are there official rules, I am assuming there are and if so can anyone point me in the right direction? Appreciate the help!
