I agree, but even getting points would be pretty rng-based. As I posted before, getting the power-ups and unlockables would be a better fit since it's more skill & route based
For unlocking and upgrading them. Choosing to upgrade one over the other may help you unlock the rest faster, and the skill to run long enough at a time to unlock what you want in an optimal way. Also, a power up won't show up if you don't unlock it or if you upgrade it enough to disable it, so you can use that to strategize. Sure, their spawn would be random, but it would still take a lot of skill.
As for how the points would be random, you get points for both coins and distance, so the run would just be a competition for the best RNG to get good power-ups in one game (like the current categories). Not a bad idea, but I don't think it would be as enjoyable
All unlockables & all power-ups categories would be analogous to 100% & 25% categories, I feel
So you’re talking about maybe 30-45 minute runs to unlock all of mega coin, or all of invisible or something like that? That might be an interesting category but I’m not going to reset my powerups for it. And racing to certain amounts of points wouldn’t be random, coins are crucial to maximum points. The more coins you get, the faster you’ll get there
