You are the head writer/developer for Mass Effect 3. For years Bioware executives have abused you, forced you to work 80 hour weeks, paid you far less than you were worth, perhaps even picked at a physical issue to humiliate you in front of your peers etc. For years you've longed to quit but couldn't because you had no other marketable skills and needed to support your family. However, yesterday you won $40 million dollars in the lottery, far more than you could ever spend. You drive right down to Bioware to quit, but realize you want more than freedom, you want REVENGE. So you keep your winnings a secret and resume business as usual, but now you are trying to come up with something that will piss off as many fanboys as possible, turning people away from Bioware/EA for years to come. What is it?
My ideas:
-Tali is genetically male with gender dysphoria and is living a lie with the female suit and fake female voice. This is revealed and he becomes Shepard's same sex romance option.
-The Reapers true motivations are benevolent and they want to transport humans to a land of eternal pleasure or something like that.
