Sorry to be a purist - I'm not even a hardcore gamer ... more of a long-time gamer (started with pong on a B&W TV in 1979).But this kind of thing does not improve one's gameplay. Rather, it makes it easier to succeed with lower skill, diligence and practice. Besides that, it reveals mystery in a way that the developers did not intend. You're supposed to stumble into that secret passage way in the dark corner, not spot it from across the room.If you want a passive experience, watch a movie.If you must do this kind of thing - and neglect yourself of the developers' vision - just crank up the brightness on your TV, most also have a sharpness control too.
