I just wrapped up my MD run through. It was. an underwhelming ending for me. And then the unskippable/fastfowardable 30 minutes of end credits with a "hidden" cutscene of illuminati meeting in the middle.
The whole "1 week later" and variant news stories depending on things you'd done was a nice touch, including that sneak about how Silhouette forms in Paris. But on a whole.. it didn't have a real feel of an ending to me. And after all the various ways to get things done, the conversations you could have rather than fights, they stuck you in a big room for a boss fight.
