It's the age old question, what would you do if you woke up in your favorite video game franchise. There are countless answers to the question; become the hero, power level your stats, speed run the plot or even take your time trying to bang all the hot side characters. All of these fantasies, the wish fulfillment, the hopes of getting to experience something impossible. It's all bull.
See when you wake up in your favorite game world you will spend the first few days freaking out, trying to figure out what happened. Once you realize where you are, and come to terms with the fact that its real, you'll figure out more information. Like how the game franchise your now a part of is a trilogy that ends with a galactic war that functionally ends everything and gets billions killed. Or how the body you woke up in belongs to a side character that dies in the opening mission as a joke. No when that happens you don't get to enjoy the splendor of being on board your favorite vessel in science fiction. You'll be focused on trying to survive. And not appear crazy to the greatest soldier in the Human Alliance, Commander Shepard.
