Star Citizen.
I just jumped out of the docking port of a ship i was clearing hostiles on (890J) to be greeted by this sight while floating in space.
EVA'ing in space between two real ships with full interiors, one 209 metres long, hundreds of KM above a real planet in 3D space, this is a massive scale with no boundary. the planet is real, its not a faked sprite outside of a boundary cube, that is it. You fly there and touch grass down there, i could EVA there in some hours...

There are no boundaries, no no go areas in the whole universe, certainly no load screens.
The last image reminds me of that scene in Star Treck First Contact where the woman is looking down at earth from on board the Enterprise.
No other game does this.
The view from my Docking port.
