Don't forget Nintendo. It's pretty damn impressive what they managed to pull off on the Switch with more or less circa-2015 Android hardware. Mario Odyssey looks beautiful and runs at a mostly stable 60fps.
What's really odd is it is now easier than ever to create games but at the same time it feels like we won't see revolutionary games like doom, quake, Goldeneye or half life ever again. These were created by small teams that could inject their personality into them.
My other theory is game creation was previously so hard, it required genius level iq teams to do it so we quite regularly got mind blowingly amazing games. Now we get cut scenes instead.
Is Ubisoft's Anvil still alive or is it just in an unknown status after they cancelled a few upcoming titles?
That said, Capcom is still doing their own thing via RE Engine...
Not sure about any others...
