lets see... there are actually a lot of things that would kick me out of mainstream games for good. securomesque copy protection (i already have a flat out "no EA game will enter this house, if you have one on your laptop, leave it in the car, or i leave it at the door. and theres NO way im walking all the way over there just for that." policy at my house) on even blizzard and valve titles.
a mutinous army of soul devouring bagels with an insatiable bloodlust and the ability to set things on fire with their minds.
game developers start making total shit, without the few occasional rays of... whatever the opposite of shit here would be, i was going to say light, but then i imagined light shining through shit and it would really be kind of an all or nothing thing. that and light isnt really the antithesis of shit. is it? yeah, terrible whatsitcalled on my part.
