I'm not sure if I am just misunderstanding the current categories, but is there not going to be a true ending category?

The second run for both characters are the “true ending”

Ah okay, is there going to be a category where you do both the first and second run in the same run? Like doing Leon A and Claire B in the same submitted run?

I'm dumb sorry, we wouldn't be able to use IGT to time runs in what I suggested

Eventually we may do an all scenario in the RE2R extended categories and just add all the IGT to make the final time like how the OG RE2 does
