I stated this elsewhere, but with some sports data, you don’t gain anything with a uniquely generated game ID. NBA teams will only play one game at most per day, and only play one other team, so if you make a key of the date and the teams playing, you uniquely identify every event. You can create an arbitrary ID for a game if you want, but it’s not actually giving you information you don’t have, and therefore is entirely redundant.
