>>19841050some people especially with video games are OCD completionists, they need every unlockable character, level, whatever. Older games used to gate this stuff behind funny challenges or cheat codes or stuff like that, but obviously they are going to want you to pay $150 for a $50 game if they think they can.
These games are especially bad with it because I don't think you have to be a super experienced player of them to understand that there is nothing special about the in-game character models, they all behave the same way and play the same way, but it doesn't matter for the kind of person who needs "Rey Mysterio '99" despite being born after 1999
