The excuse I usually see in Science Fiction or Fantasy of "Magic!/Technology!". Now now, I know the quote "Any sufficiently advanced technology is indistinguishable from magic"... That quote, my ass. Behind every bit of technology, there's a theory. While I don't want to demand a theoretical and scientific thesis approved by peer review, I do give out huge freaking points to the writers if they're willing to give me the basic theory of how it works. A shining example of what I'm talking about is something I still find incredibly exciting to read every time I think about it... And that... Is this http://cnc.wikia.com/wiki/Living_With_Tiberium_(blog)
It was created for Command & Conquer 3: Tiberium Wars where the studio asked a couple of people from universities to write a paper on Tiberium as if it was the real deal. Now, say what you want about the game, but that right there, is what I would love to see in every single game. A thorough explanation of the main thing of the game and I'll be happy.
Captcha: More Better. Exactly, Captcha. More of that and everything would be a bit better
