Leaving my private life out of this and going back to gaming. I just want a satisfying and appropriate ending to a game.
Some happy, some a bit sad and some that combine the two. I personally like things to be relatively well tied up at the end of the game, even if it's just hinted at. I don't want everything spelled out for me, a little bit left ambigious and the player having to use their imagination a bit as well.
I always quite liked endings of games or films that leave people thinking 'Do you think that...?'. I quite like reading peoples theories on what could happen next or what the characters would do next. It makes the game feel like a bit more immersive.
