Good story
A lot of choices that actually matter
A decent time between updates
I don't really mind about graphics but better is preferred, but if I see characters that I like the look of then I'm more likely to play.
I think if it was unlocked from the beginning then I just defeats the purpose of even playing the game so I think it should gradually unlock as you progress.
It can also be a good way to see if your missing any scenes your and how many.
I hate when the game forces you to do something or puts you down a specific path without at least giving me a choice.
The really loud music that I always have to turn down.
Ending on a cliff-hanger just to wait possibly months or longer for the next update or it gets abandoned.
And like many...
