100% sounds like a category that could be interesting, but its up to you how you want it to work. Right now, I'm thinking of two options for how the category can work out. In both, you have to collect every ball on every map.

1. You can turn racing off mid-map to change maps faster, meaning you don't need to finish each race. Downside of this is that lag might be a bigger problem, but it would be interesting to see routing. The run would be timed based on real-time as you wouldn't see end of race times.
2. Along with collecting the marbles, you also need to finish each course. Benefit of this is timings can be more consistent, due to in game time being usable, but would also take longer to complete runs.

I think option 1 is interesting, and for retimes we'll use SPRT or yt-frame-retimer.

The goal is to complete all 20 tracks and get their marbles. Because it automatically gives you the marble forever whenever you collect it, you have to show you got the marble by going entirely through it.

I think it would kind of work for ILs too, but if we did do it for ILs, it would have to be option 2 instead of option 1.

Honestly, I think the best option would be a mix of them. You have to do all the races at least once, but not more than that. Also, what about the 250 races marble? Would that be counted or not? I would say yes if pipe nightmares was still around, but now I'm not so sure.

Race count marbles wouldn't be in consideration for this. Only marbles that are collectible on each track, and maybe lobby marbles if you would want that too. No # of race marbles or anything like that. If we did lobby marbles, it would have to be real time. I am alright with either option.

OK, I don't really care which. Maybe we could have a subcategory for lobby marbles?

I mean, all marbles in tracks + lobby marbles
