Another great drug-addled set piece is the John Woo-influenced shootout in the brick works/drug factory, where as you shoot the sacks, your vision becomes increasingly psychedelic and Panjabi MC's Jogi, his wonderful remix of the Bollywood classic Mundian to Bach Ke, kicks in.
For me, in that context, the music blended perfectly. Aceeeed, as the young ones used to say.
I wouldn't mind seeing it remastered against latest engine, along with various other tweaks, such as: give Min and the Minions more airtime, with more meaningful player interactions, and remove mandatory side-missions (such as Shangri-La) -- this also applies in spades to FC5.
Being there was wonderful, but it didn't use the HTC wands and natch you can't see the keyboard controls. If I'd learnt it on a gamepad, it might have been a goer. Also, non-VR optimised ports = motion sickness.
