I get what you mean, but 99.9% of the time I’m buying it day one anyway
Well, no one is saying you can’t buy it on day one, just don’t buy it on day minus one.
On the day it comes out you can just check some reviews first and then reaffirm your decision to buy, or you may hear about something you weren’t aware of, and then decide not to buy.
Also by doing this, you help all your other fellow gamers, by diminishing the importance of the pre-order and the shenanigans that go with it.
