I think that what should happen is, on the game's main site, there should be a huge half-page banner. On every retail (in-store) version of the game, there should be a giant sticker. And if you can buy it online, you should have to read a very simple but very large disclaimer.
The banner, sticker, and disclaimer should all say the same thing.
They should both say:
THIS IS NOT FALLOUT 3.
Then, maybe - just maybe, I pray - people would stop comparing these two games!
But you take an extremist stance to it, if your profile is anything to go by.
And stop comparing one game to another, even if it has the same name in the title (you idiots who compare FO:NV to FO3? Yeah, I'm talking TO YOU).
As if to say that anyone who compares the two games is a lesser human being.
