could you run it?

No because you would be "setting a seed" which is against the rules, plus the person who gave it to you could know it is a very good seed and that would be unfair.

Exactly

Then the run should be called selected seed instead of random, and so it cant be RSG

ok thank you can close the thing now

but..... why? there's no difference and you could just...… lie.

In the Random Seed category, you have to show in your video creating the new world to speedrun on, without touching the seed option.

@LukeSaward yeah because you can look up the seed and find strongholds n shit
