If I can, I try to get my pre-orders through Best Buy's in-store pickup, which means I can simply walk in the store and pickup my order. It's essentially the same as going in and buying the game on launch day, except I'm guaranteed a copy that I've already paid for. If I don't pre-order, there's a chance the store either won't get any copies by release day or they may sell out of them by the time I get there after work.
Also, try as I might, there's been several times where I haven't been able to get a copy from Best Buy for one reason or another. That leaves Amazon as my only choice. So, in that case, pre-ordering means I'll get my package on launch day, typically in the early afternoon.
So, for me, it's less about the pre-order bonuses and more about the logistics. I want to play a game on the day it comes out. I've usually planned to have free time specifically to play the game on release. So pre-ordering means I spend less time looking for a copy of a game I already know 100% that I'll enjoy and more time actually playing the game.
Honestly, if I can, I always get physical. If I buy a digital copy, there's no guarantee that the store I bought it from won't take it back or something like that.
OP didn't mention games that have Denuvo in them. They simply mentioned pre-ordering games.
And before anyone says this is a post about Denuvo, OP's comment was phrased in such a way that it could sound like, "Why would anyone pre-order games in the first place in 2024, regardless of whether or not it has Denuvo?"
Yeah, it's still pretty common for big publishers to sell their games physically. Games from smaller devs that self-publish are usually only sold digitally, though they can sometimes end up getting published physically later on if they get popular enough.
Edit: Or were you talking about Best Buy and Amazon selling physical games?
