"here is this fun simple game called Rocket League, its about playing something like soccer but with cars, a few years ago I paid around 20 dollars for it, back then you were able to earn all the garments (hats, wheels, et al) for your cars just by playing the game, 30 minutes per day were more than enough to get all the wardrobe"

Not true. It had crates that dropped and you had to buy keys to unlock them for randomized drops. At least now you know what you're buying if you choose to unlock an item.

"a game I spend more than 2000 hours is now a game I hate -and don’t play, of course-."

This seems ridiculous to me. The game is the same, if you love the game, why would you stop playing because of cosmetics? Just don't buy them, use the free ones they give out. Or, rid yourself of the notion you must have every cosmetic, and kick a game you love that is also a live service a few bucks now and again for something you particularly like.

There's so many terrible free to play games out there with dark patterns and predatory tactics, Rocket League is hardly the enemy here.
