"this is ilegal" you should read your terms of service next time you log in, there is a reason you have to click "I accept" because you have literally agreed to forfeit any rights like that as you agreed they can for any reason shut off access to the game in partial or whole for any reason, they do not need to inform you of that decision either.
If SEGA is selling you anything - knowing theyll remove it in a couple months without mentioning it IS illegal and worth a charge back
Not if you have agreed to forfeit rights, and they have a digital signature of you doing that... you dont understand how this works do you?
Now i see why this wasn't released in Europe. Companies actually get fucked there for doing shit like this.
