I would definitely like to see it because even with the explanation, I'm still finding it hard to understand what or how it works. Maybe I should seek YouTube's help.
If it's a game where my decision impacts on the game's end, I would definitely like to do something that's going to offer me a huge sense of satisfaction no matter what.
If the main points in the game aren't highlighted in the trailers, I wouldn't really call it a good one because it must have something that's going to be like a call to action.
Personally, I don't think that I have had an act in game made me feel so bad like that in Spec Ops: The Line. The faces of the innocent woman and children can't get out of my head.
I don't really know or think of it that way - being that having completionist tendency take away my passion for the gaming but rather it will get you addicted to games.
