Choices count. I would like to have endings ranging from death, only because so many people seem to enjoy watching their character die, as self-sacrifice or even a betrayal depending on how the story develops - to endings where my character survives with some friends and a love interest. And who survives can depend on what choices I make through out the game. I don't need to know what they do after the game is over, just that sometimes they survived it together. I don't mind a sad, depressing ending as long as there is a celebratory survival ending to balance it out.
A nice fire, some fireworks, dancing a look and smile for your love interest and a moment of silence for those who didn't make it
One of my favorite things in ME2 was just playing with different options and seeing what would happen. I don't mind someone dying in one game if there is an option of saving them in another. VS was always hard to do, but I knew I could save Kaidan or Ash the next time I played.
For me, games are too expensive to just play once. Even on sale, I want to WANT to play more than once. ME1, and 2 gave me that. All of the DA games have given me that ability to replay and I'm enjoying DAI a lot. Actually, all of the Bioware games other than ME3 gave me that encouragement to play over and over. ME3 took the mod to do this.
