Unfortunately, they didn't fix the trinary choice at the end of Mass Effect 3. Martin Sheen just prattles on for about 20 minutes about the end and what the choices are, and then you're given 3 paths and just enough time to reach one of them. They never tell you what each one does. Sure, you could pause the game and look it up, but at that point you kinda just want it to end. It's three deus ex machinas, they're all explained ad nauseum, but they aren't identified. Then they play a short cinematic, and then it's over. A lot of people complained about this upon release, and I'm annoyed they did not fix it.
It's even worse. The trinary choice and deus ex machina was the fix.
From Wikipedia
Upon its release on March 6, 2012, for the PlayStation 3, Xbox 360, and Windows, Mass Effect 3 generated controversy when its ending was poorly received by players who felt that it did not meet their expectations. Criticisms included the ending rendering character choices inconsequential, a general lack of closure, plot holes, and narrative inconsistency.
On June 26, 2012, developers released an Extended Cut as downloadable content (DLC) intended to clarify the endings and remedy fan concerns. The initial announcement of the development of add-on content to amend the ending as well as the subsequent release of Extended Cut sparked debates over the treatment of video games as art and whether BioWare should have to alter their vision of the work in response to external pressure, regardless of its quality.
