Its not abuse and more just a selling point. If its widely accepted and you look at examples of games like
POE 2 or even
Diablo 4, players will pay to access the game early for whatever reason. Being given the option isnt bad, you can simply not play early and wait for the release day. Gaming companies also like to create FOMO. So if you can resist the urge, good for you, but its not an abusive tactic, no more than including DLCs with more expensive version of the game in my opinion.
POE2 maybe a good game, but i can't help but wonder why people would pay for a game that will eventually be f2p
I have roughly 30-50 hours of game time in POE, which isnt a lot, but i did enough in there for myself that paying 30 bucks to play the games successor well before it releases to see the game go through changes wasnt a hefty price. Had nothing to really do with the early access part and more for wanting to support the devs, they are nothing like Blizzard or Bungie and for what
POE 2 released so far, it is quite a lot of content in an early access eventually f2p game.
Now, I expect you can get your review out on social media before others and thus get paid more for the clicks.
This right here, plenty of gaming personalities that want to be the first with reviews, playthroughs, cheats, "10 things you should blah blah blah in this game" videos.
