This may sound obvious but one of the main reasons I didn't ever buy RoS on Ps4 was because I thought you needed a PSN sub to play, even for solo mode and I didn't find any threads to confirm otherwise. Needless to say I bought the game the other day and found for solo mode you don't need to have a PSN sub and just wanted to let people who were unsure about this point.

I know probs most ppl who have a PS4 have the sub, but this is just for those who never knew this.
