So finally found out how to register physical games to get gold coins. I only got my Switch about 2 months ago so yeah... Turns out only 3 out of 7 of my games I could get coins for. The others expired like MK8 and Smash, etc. I know they came out a long time ago but kind of bs because I still bought them almost near full price at like 50 and 55 dollars new. I don't see why they have to expire if they keep the price near launch prices. Sure suppose to entice you to buy game when first comes out but it screws over new switch owners.
