@kylania... which i didn't denied ... i simply stated facts ...
i will not go into things like why games can't be secure enough
because if they were, you would not find computer capable to run that game
(ever seen cpu/ram overhead on secured memory allocator for example?)
some things aren't possible as you not making security software
(which btw. become obsolete within 30days after release)
so while trusted environment sounds magically simple ... it isn't
ofcourse we will try to make things better and safer ...
