What did he mean by this?

He wants to know if it's good.

He thinks it's good but isn't sure.
It's good, isn't it?

This is a pleasant experience. He's dying peacefully with his son by his side.

He never thought of Solid as his son though. In the end he did come to respect him a lot.

I think it means he's finally dying for good, in a peaceful way, and it's a good thing.

He's talking about the cigar.

That's some good shit.

>im foxdied but things will be ok, yes? dies

He's asking The Boss if he did good this time.

>>383423531
He's asking if the 16 hours of cutscenes you had to sit through were worth it
He dies when he realizes that they were not

He was tired of all the BS he and his comrades dealt with over the years, and was glad that he could die with his goals more or less wrapped up and the world not being as fucked under the Patriot AIs.

It's Kojima speaking through Big Boss. He said basically "this scene" was good isn't it? Or you can interpret it was the cigar.

The BS they dealt with was caused by themselves.
