I played through um... what's it called... the place where you have to get the horn of Jergen Windcaller, at night, on minimum brightness, TV adjusted to low contrast, brightness, and low color (Looks dreary and... just kinda... bad...) on max difficulty with ceiling fan going, doors open (It was winter so it was friggin cold, plus my room is basically a one room cabin [with no insulation] in the back yard, making it even colder and windier.) And i went in with nothing but a set of nonupgraded fur armor, a pickaxe and a few torches, no magic, and only whirlwind sprint for shouts. Volume up high too, on a big TV.
I was no longer playing Skyrim, i was IN Skyrim.
Yeeeeah... i like to make video games as an immersive experience as possible... and some people say i take it too far. (Every person i've ever told, actually...)
In all reality, i try to play in as close to those conditions as i can, but the opportunities are rather few and far between... saddly
