You only get the 1500 renown for completing the training course. In stock SH3 you started with no renown if you skipped the course, but in GWX you start out with 500 points. (Enough to acquire upgraded hydrophones) If you completed the training course however, you got the 1500 renown to start with. In GWX all you need to do complete one training mission to get the renown. (Navigation is quickest and easiest, obviously)
