So I get asked this question a lot, for some reason. You might go 'Oh my god, I can't believe how nerdy this is', but Here's why, as told by an anonymous member of /tg/.
"It is the scale and depth. Anything can happen, and it does, all day, every day, at 250% maximum awesome. It is the over-the-top-80's, super-gritty-90's, and depth-demanding-2K's all blended together into one multimedia story. It harkens to the classic tales of the Gothic Age, the epic fables of Northern Europe, the darkness and detached sentimentalism of WW1, the corrupt tales of the urban underworld, the mind-warping fantasies of Lovecraft, and all while maintaining a sense of dark humor and romantic heroism."
And that just about sums it up, really.
Stay awesome, everyone.
