So there are a few games which are completely banned in my hometown which I plan on buying and playing during my vacation in a country where they are allowed, once I get there I will change my Steam store location and buy them, my question is, once I buy them and play them then get back to my hometown where these games are banned, what exactly will happen in this situation?
