Well, it would be nice if one of these games was eventually made into a movie...but done right of course.
Live action movies of Halo, Bioshock, Splinter Cell, Uncharted, and Mass Effect would be amazing. At least we know the technology has caught up enough for a film to be feasible technically. The story...well we all know what happens most of the time when books get turned into movies (Eragon the movie was so bad it made kids cry).
