According to last month's issue of Game Informer, the infamous ME3 Ending was in the "Top 10 Dissapointments" at number 5 BioWare never "made a case" for the original ending.
"Some fans loved the ending of Mass Effect 3. Others hated it. At first BioWare staunchly defended its right to make creative descisions, whether popular or not. Then, it changed course and released DLC that expanded (but didn't drastically alter) the ending - leaving both those its defenders and detractors unsatisfied. Worst of all, the studio never tried to make a case for its original ending."
I guess that means they wanted details on why they thought it was good and was worth defending. What do you guys think?
