There is no way to prove that claim true or false. People could've been idiots, or they could've gone: 'oh, this must be an error that will get fixed'
Or people really wanted to get Skyrim: Legendary Edition. For more than four hours (since that's when I remember that) the glitch was fixed so unless you have proof that Skyrim scored big enough during the glitch all I can say is maybe people only wanted the game more than the others. I know I would've voted for it regardless of the glitch because I love the Elder Scrolls games and would also like the Legendary Edition since I was so stupid enough to grab the standard edition.
EDIT: Also I'm siding with you R4gn4r0k so don't think this comment was directed at you.
or, you know,I was exaggerating and not everything has to be taken so literally
