rip score

hello. good afternoon. i am having fun in skate. i’ve been playing the game since it came out to the public , and i actually like it due to how much fun it’s been having. i am also going for all the achievements. one achievement caught my eye and its one that says we need to have 11,000 rip score in order to get it. the only ways to earn rip score is to finish all the main line missions, and from boxes when u get something. by the end of everything unlocked/completed i’ve had 6k rip score. it seems like in order to achieve that i’ll have to do using real world money seeing as you get rip score when u get items from the shop. is there any way in the distant/close future we can get more ways/opportunities to earn rip score ? that’s really all i had to recommend. thank you
