has anyone done a speedrun were they complete AA in all versions? like all versions but AA instead of RSG.

Would take a GIANT amount of time to finish

1.0 and 1.7 is impossible to complete (On 1.0 they messed up coding sniper duel but fixed it in 1.1) (for 1.7 adventuring time is impossible because you can’t get it if you enter the end or nether bc it counts overworld biomes and only overworld biomes but to get it you need to get another achievement where you need to enter another dimension)

I'm assuming this is versions 1.12 to 1.18, as it says advancements. If we assume that with no resets, each version would take around 9 hours from an experienced player as that's how often lightning occurs (i know it isn't needed in 1.12 but it still seems a reasonable estimate), this would take 63 hours to complete and would need to be done in one sitting as av runs are exploitable otherwise. As av has a health warning on it at the moment, I imagine the moderators would hugely discourage an aav run due to the health risks. Also, few people have a computer that could record 63 hours of uninterrupted footage, so it's not practical anyway.

"would need to be done in one sitting as av runs are exploitable otherwise" Segmenting is explicitly allowed in AA categories.

But it's explicitly disallowed in av categories

That would take a couple days lmao

Yes version

"But it's explicitly disallowed in av categories" Simple compromise, require any segments to split during one of the versions instead of in between.
