I've not seen or heard of anyone buying tix, I'm sitting at 20k after finishing the Skate pass weeks ago. They also never said they are halting development on player created parks, it's a massive undertaking to create the kind of system that we would expect, not to mention hosting the files, making them available and downloadable, along with the UI, bugtesting. That is a monolithic undertaking.
I'm not a fan of the flashy cosmetics either but people are buying them, so clearly there is interest in them. There's magnitudes more in realistic items to obtain, and you hardly ever see anyone running any of the skins except the Grim Reaper one.
We have no idea what the progression will look like when the game is finished - which it isn't. Right now, the progression seems pretty fair to me, you get an alright selection of items and those who've been playing since launch have the most stuff.
They said for updating the boneless, they've had to basically completely rebuild how they're performed in-game. Adding tricks is not some simple thing of chucking a few keyframes, it has to look, sound and feel good every single time. You said you've been playtesting for 3 years, you're here bashing what's essentially still a playtest, not a finished game. I don't think you've got a healthy perspective on the title at all
