Skyrim’s followers have a maximum carry weight and won’t let you trade them any items after they exceed it. That is, if you TRADE them the items! You can just Hold E/talk to them and go into interaction mode and order them to pick up things from the ground. They will happily do so without complains regardless of their carry weight status, extremely helpful for collecting a bunch of dwemer junk to smelt down into ingots for smithing - those things are heavy!
Steam specifically designed the system to make it easier for developers to handle pricing for multiple regions, and in their SteamWorks documentation on pricing for developers in the Regional Pricing Recommendations section they say:
yet their suggested pricing has not changed since the program was introduced in 2022. If they don’t want to commit to keeping the pricing up to date, as they themselves promise, then retire the program and make publishers set the price themselves on every game.
