The lights are on
I'm hoping that your decisions are tougher and have more consequences. Sure, it was possible for your team members to die and even for Shepard to die, but it was easily avoidable by doing their quests and such. I want the story to build a real connection between you and the characters, and then make you choose who lives and who dies. That would be an awesome ending.
Or maybe a choice of saving your female love interest or yourself. Things like that.
