An update to provide from EA's unhelpful live chat support:
This particular EA chat support technician, Jatin, stated that the pre-order bonus of NHL '94 Rewind was only available for those who pre-ordered the game directly from a first party retailer, that being directly from Microsoft or Sony and their respective online stores.
I was given this false pretense despite the fact that EA's website for the pre-order bonus of NHL '94 Rewind never disclosed that the game will only be available from specific retailers.
https://www.ea.com/games/nhl/nhl-21/news/nhl-94-rewind
"Pre-order NHL® 21 and you’ll be able to play NHL 94 Rewind on October 30, 2020!"
That's exactly what their own website states.
Way to mislead and lie to your customers, EA.
