Accumulating Bodily Regional Exclusives

I’m a US collector and my assortment is 95% ESRB rated. Nonetheless I like amassing bodily Xbox One/Collection X video games from different areas that have been NOT launched bodily in North America. I’ve by no means been capable of finding a very good supply of data or a definitive listing. More often than not I simply find yourself utilizing eBay to determine if one thing does or doesn’t exist bodily. Does anybody know of a very good useful resource to determine what video games are unique to what areas?
