>>27035905One of the reasons is because Sega for the longest time had permissions autism, but they've changed things up once they realized "Oh fuck, you mean people actually might want to BUY games their favorite streamers enjoy playing?".
As for every vtuber starting with 0, yeah it can be a bit obnoxious, but there's a good reason at least. The Wii U/PS3 HD Collection of 1/2 is Japan onry, and there's a one in a million chance of any vtuber being smart enough to own both an original copy of the game, a PS2, and an upscaler of any kind to properly play it. That, or be that much of a weeb to import the PS3/Wii U versions.
