But the biggest question would be what kind of plot the movie would be. Follow the games? Then you would have a lot of disappointed fans that won't be able to see "their" Shepard on the big screen. And by doing a movie based on the games then they are confirming that there is a "canon" story to the games. I'm not sure I would want to have a "canon" way of the story.
But I would still like to see a movie set in the ME universe, perhaps with different characters.
