I can deal with non-specific noises from outside my room, like traffic, loud neighbours etc. Can't handle any noise from inside my room, especially if I know what the source is. Light-wise, I pull the cable from the 360 power adapter to kill the orange light, unplug routers/ethernet switches, pull the power cable from my desktop PC (ethernet port orange and green lights plus motherboard power LED), fuss with curtains and generally freakout over even the slightest light source. Seriously considering black-out curtains.
I have even been kept awake by the power light on my closed macbook pulsing on and off, even though it was in a closed bag. I could see the light through the zip.
There's probably more. I threw in some racing games as those are usually great when they turn the assists off. You also might want to look up some of the RTS quick looks, like this one of Napoleon: Total War.
