KOTOR would be the best choice. The cinematics are fairly detailed. The trick would be to take one quest and make it the central story. I don't think anyone would be interested in the court proceedings of the Kolto fish men - but everyone would be interested in the destruction of the Jedi Temple on Dantooine.
For action seqeunces, play through the game recording the quests which fit into the storyline which DOESN"T include opening every single damn box...and you might be on to something.
As far as something similar to RvB - those cats found a 'glitch' in Halo's code which made it possible to exploit the character's movements so they could control things to a large degree...
