It's fucking bonkers getting all the gaps as well in my opinion.... must have spent at least 6 months, every evening as a teenager just trying to get all the gaps in THPS4 once I'd ran out of shit to do. Nuts.
I used to do this glitch that I don't know if anyone else ever found it but if you hold the stick back and turn clock wise or counter clockwise you get thinner and thinner until you let go. Lol
At about 27:53 the guy in the picture on the goals menu is in T-pose. I'm not sure if the cutscene skip bugs that(which would be incredible) or if this game is just Like That.
I think I missed the explanaition and I cant find it, but why does he need to get gaps in each level? I dont remember gaps being part of the progression, aside from the secret skaters.
