Mostly it is due to the glasses and the effect the glasses have on the wearer.
Having recently seen my first 3D movie at a theater last night, I can say that yes it does look incredible, but I have significant eye strain, that is still bothering me the next day.
Others I have talked to said they get headaches from the 3D glasses, others just hate having to wear them due to comfort, interfering with their normal glasses or not used to wearing glasses..
Sorry, no one I have talked to is willing to veg out for an hour or 2 in the evenings with 3D glasses on.
I am really not willing to do it for games either. I'd rather have a few hours gaming in 2D, than a short duration with headaches in 3D.
Highlander 2 doesn't exist. It was never made, never released. Just move on to Highlander 3 then the TV show, then stop. Don't go any farther.
You were warned!
There are little things that could be fairly important where they don't render things correctly. Just search and you'll find quite a few examples and work arounds.
The most basic one I can't understand is by a basic inset or outset button renders with a solid black line in IE8? The work around is to color each side of the border individually with the custom color you need to make it look inset or outset.
Real Programs don't use shared text. Otherwise, how can they use functions for scratch space after they are finished calling them?
