Should Counter Strike be so BRIGHT AND COLOURFUL?

CS2’s levels are suspiciously bright and colourful. But does light REALLY bleed like this? I could have gone outside to take a look, but instead HACKED CS 1.6 to display raytracing. As for whether it should be... feel free to discuss whether it should be in the comments section :P XASH raytracing - CS:GO maps in 1.6 - 0:00 - BRIGHT 0:24 - CS 1.6 raytracing?! 1:31 - History of CS lighting 4:01 - Dust2 compared 5:29 - Italy compared 6:32 - Other maps 8:34 - Office
