I want to know what's the reality of the Digital Code. I want to buy Tekken 7 for my XBox One S. I saw an advertisement on OLX in which a guy is selling XBox One S Digital Code for Tekken 7 which he claims can be used on Tekken 7 game and it will remain valid. I confirmed with him that is it a Game Pass Code but he said that the code will work only on Tekken 7 and will not expire after 1 month. Is it true or a scam? What is the reality of these Digital Codes. To me they seems CD key
