I don't agree with this sentiment. AC: Odyssey had problems, I'll admit and it's cash shop did affect the game (xp bonus and items with stats), but the game was still amazing despite those issues.
I know plenty of other games have issue with this though, so I know you're not just blowing smoke and/or over reacting.
Simply put, I don't believe it's a foregone conclusion that a game with MTX is automatically going to be bad or that the MTX will automatically interfere with or hinder the quality of the game or it's entertainment value in any meaningful way. It's a possibility, sure, but I'll wait for that to be proven before I judge and not act like a pessimistic stick in the mud.
