livid pendant
not sure how much i can help without falling under the 'general discussion allowed, but no assisting piracy' rule. the following info is true for the legit game, idk if pirated copies will work the same:
factorio saves are usually kept in appdata/roaming/factorio so you might just have to copy them and send them from one pc to the other after playing. if you have a standalone portable install instead, then the saves are all in the .exe directory and you can put the entire game with its saves and mods on a USB or a portable hard drive
