There's two different things, but a part of the same wider problem of microtransactions in full priced games - gambling mechanics and incremental costs. Gambling mechanics are obvious - they are the FIFA packs and gaming loot boxes with random chance.
In CTR, it's incremental costs. What they do is wave items in front of those with addictive/easily led personalities and say for a bit more money you can have it. Add to that the items being time limited and rotated off sale for other items and it puts a 'time is of the essence' factor on to it too. It's all designed to milk money on the drip from those who have a tendency to collect, to not understand how money adds up etc. There have been stories of problem gamblers and hoarders/collectors playing games to replace those bad tendencies who have then found them shoehorned in to games and being hooked in exactly the same way.
This is a woeful practice at the best of times, but with CTR they released the game without these extra costs with no indication they were coming, then inserted them a month after release. Conveniently once the reviews and first peak sales were in.
It's unethical business practice and, quite frankly, predatory. I don't use that word lightly either, but that's what they're doing - they aren't producing a quality product to want people to buy them; they are creating insidious mechanics that prey on the weak.
