Plenty of games have great characters and excellent world-building. Quite a few pose interesting questions, make you face hard dilemmas and leave you pondering long after you're done playing. Several make you immerse yourself in the world and identify with the characters so much that a particular event in their plot will provoke very strong feelings.
But none of those have a plot you can take and make a good movie out of it. Hollywood could very likely pick one of these games and make a great movie based on it, but not by focusing on the plot.
For example, I would be thrilled to watch a movie based on Dragon Age or Fallout. I might like a movie based on Borderlands, perhaps. On the other hand, I'm pretty sure I wouldn't enjoy a movie based on The Last of Us or Uncharted or The Talos Principles. And all of those games are among my favorites precisely because I enjoyed their world, characters, themes and choices.
