So... the thing that we've all be looking forward to about this game, ever since it was Versus and then reannounced as XV, namely the invasion and the presumed destruction/escape from the city.
That's been cut, and is instead relegated to the cgi film...
I thought for sure it was still in the game, it was the main thing that had me interested.
So instead of that potentially amazing opening we get the cast pushing a broken car and doing a mundane tutorial monster quest.
It happens off-screen in the game now. Noctis and friends find out about it through a newspaper.
