I've completed about 400 challenges now with only 4 more videos to unlock. Next, I think I'm going to complete a few more platinum scores before focusing on completing more of the skater specific challenges.
The gameplay loop is just so satisfying that any excuse to play just a little more, complete another challenge here or there, means that it'll be a long time before I've had my fill of this. I'll never unlock the 100K or 10hr trick challenges but I'll certainly be playing for a long time to come.
This would certainly be in my GotY shortlist for 2020, if I was a person who made those kind of lists.
100% THPS1 this morning and I'm currently about 93% on THPS2, just need a few more objectives to unlock Skater Haven level. Even though I'm nearing the end I'm still having a complete blast with it, I love going back to the areas and exploring and finding all the gaps, very addicting gameplay.
There are two kicker ramps leading up to each building that you can jump up when you upgrade your ollie stats a little. It's not the big building across from the gym, it's the two smaller ones near the far end of the level.
The NYC hidden tape is a pain in the ass. I found it best to go slowly across the first rebar and then hold left and Y as I jumped to try and get onto the second rebar.
