Everybody knows that the discerning LEGO fan can not be seen dead buying children's toys. No, they collect LEGO sets that reflect their more adult tastes, like fancy architecture and expensive sweaters.
This mock-up, then, is a nice compromise. It's technically Halo LEGO, being a Forerunner Spire, but because that's a building, and it's presented as part of LEGO's swank architecture line, those who love their Halo, love their LEGO and love their expensive Scandinavian furniture can continue living their lives without fear of compromising their carefully-cultivated designer identity!
