I could spend dozens of hours just exploring Night City like a tourist.

I have spent dozens of hours exploring Night City like a tourist, I mean, but I could spend dozens more (and almost certainly will, if I ever get a graphics card that can run it decently with ray casting).

And then there's actually playing the game, of course, which for me has been fun from day one, but then again the PC version seems to have been spared most of the bugs.
