It didn't make sense to me that people are pre-ordering digital copies at first too, then I remember mtx and streamers which didn't exist back then.

It's the boiling frog syndrome. Gradual implementation of predatory monetization practices like mtx and gachas have made us grown numb to being treated like cash cows for unfinished products.

The latest generation of gamers probably see this as a norm. It's up to us oldies to remind them about the good ol' days when you only pay once for finished products.

I mean, I usually buy physical and sometimes they do run out. Metroid prime remastered for instance was a pain to get. Granted it's probably not the norm but it happens.
