I dunno, eesiginfo.
When DVDs first came out they were hyped as immersive and having viewer interaction. There were some DVD titles where I could choose the camera angle, or alternate scenes. My neighbour at the time was excited about it and showed me a few movies like that.
That was not exactly amazing: why not just watch the cut scenes via the DVD menu.
Games are supposed to be fun: nobody wants to sort of participate in a few scenes that have strictly limited options and then watch video for a while, then rondo. What's the point? It's the worst of both worlds.
Take Deus Ex for example. In Deus Ex HR, there were cut scenes and voice overs (ie: orders) from Command Central, and these things either broke the game play or imposed choices on me.
In Deus Ex Invisible War I could choose my path modulo there being only 6 outcomes - but I was often surprised how my choices influenced the outcome. Maybe a faction leader nagged me but I could tell him/her to F off.
I think Deus Ex IW offers a way forward: many and surprising choices without a fascist director imposing a decision tree on the player... yes you ultimately have to get to the end of the game but there are many paths to the end state and they are not tightly scripted.
