People have been saying this game is exciting because of the lack of mtx, but it seems to me that any big rpg gets a lot of attention. Eldan Ring got similar praise last year. Bioware was making these kinds of games fairly consistently about a decade ago and then stopped to make shit like Anthem. It's a design decision not a budget problem.
Microtransactions come with specific challenges. Specifically, you have to give the players a reason to pay them, and that's usually done by making the game purpously worse for those who don't pay.
Or the other trend these days, Wich is to remove content from the base game and sell it as dlc or just money-gate it even if it's on the base disk/release.
I don't necessarily believe this to be universal. I've played plenty of games with cosmetic mtx that I can absolutely play without the desire or need to spend money.
