Thanks for suggestions. I wouldn't ask this question if all my drivers were not up-to-date.
It inspired me to do some more playing. The only thing which worked was: force it to use the integrated Intel gfx, switch Windows screen resolution down from the native 1920x1080 down to 1600x900. Then I could get into game. I could then set its resolution off default "desktop" to explicit 1600x900; which allowed me to restore desktop to full! It would then run OK in a 1600x900 window.
So it looks like, for me, 1920x1080 crashed it. The NVidia was a no-go at any resolution. Not the end of the world, but a bit disappointing --- I expected both of those to work?
