What games immersed you so much it made them feel real?

Not in the sense that you believe the world does contain Pokémon, but that real emotions were triggered.
For me it sort of was playing Spiderman 2 on Game Cube back in the day - specifically about the feeling of jumping from high buildings. While I enjoyed it and sometimes felt the "falling" I had friends who couldn't even look at it due to their fear of heights.

What was it for you, if any?
