It’s not polite, it’s calling him out. Trump will say/lie about anything. At one point Trump said exactly this. He didn’t mean it, he just said some shit.
Bernie is repeating his own words because occasionally Trump says something good without any intent to follow up.
So Bernie is taking him at his word. He knows Trump will never do it, but if he can call the hypocrite out and trick him into agreeing, why not?
To want to talk about 4D Chess? There it is.
I know that’s a direct quote from the developer, but I disagree that is what actually happened.
It seems clear to me the prototype did more heavy lifting than he’s giving credit. He clearly had an established vision beginning with the prototype. He spent three years thinking 3D was the best way to achieve that goal, but that goal was clearly based on the prototype. At some point it was clear that 3D was drifting away from the core, so the switch to 2D and a renewed focus was the answer.
It’s also clear that they had a distinct art style in mind from the start.
And that existing engines couldn’t meet that distinct art style.
That home-brew engine is what gives the game its unique look and can allow for unique game elements, but that initial prototype was clearly the guide.
