Exactly what I mean by specific scenarios. If a player is spending most of his time on PlayStation but spending his MTX money on another platform, then this becomes a pretty bad deal for PlayStation. It's how business gets made, "You need something I have, and I want something you have"
But it only works that way with the PlayStation. Do you even play Fortnite or have any frame of reference with this? I can buy VBucks on the PC, and then those are usable on the Android, Switch, or Xbox if I am playing on one of those and want to get a skin. But if I buy VBucks and then play on my PS5 those VBucks aren't usable there.
