Would you rather play a game with a dark, gloomy storyline or a game with a cheerful, happy storyline?
I would like the dark game better, games with a darker storyline seem to be much better than cheerful games imo. Even though Kingdom Hearts has a "cheerful" storyline, the backstory to it is quite dark and sad.

Call me a sadist if you want, but if a game has a storyline where horrible things happen to the main character (saw family murdered etc.) it makes me feel much more immersed. Maybe it's because of the state our world is in right now...
