imagine a world where people figure out if they can actually do something before announcing it

"guys i will release a fully working time machine! what should i call it

"
"wow thats so cool how did you figure out how to do that?"
".....errrrrr i didn't, do you know how? im stuck please help me"
afaik there is no way at the min to mod files that have animations as the repacking process strips everything out except the model + textures which means they will not work in game, so you will be limited to editing very minor stuff (generally stuff that has no animation, i.e tree's or something)
