Well in 2004 playing with physics objects counted. But there were other things to look at - Eli's lab was full of shit. Kliener's lab had places to run and jump around on. 
And they weren't that long. But yeah with Alyx I expect lots of cutscenes where I'm locked in an area with invisible walls and if I don't do exactly what the devs wanted then I get pushed into the place they want me to play properly
