All other NSMB games have this category, and even the origional has this category. Why is this not a category on these boards yet?

The title speaks for itself

IGT is a realiable timing method that balances out the load differences from Digital and Cart. We already have a calculator for IGT. We can still have RTA times on the boards, but the rankings will be based off of IGT.

In this category you go through all of the time trials and beat them all as fast as you can RTA. A lot of people have been hoping for time trials on the leaderboards, and I think this is the closest we could get to that.

As an addition to the current Level Leaderboards, I propose that we could possibly add some for all of the sub areas? This was just a random idea I have had recently

You complete the game while getting all moons that are in 2d or are part of a 2d area (like Past the Chasm Lifts in Cascade). Will be like All Sub Areas in that you have to start from a new save file.
