I don't really understand any benefit to showing off a game so early in production. Like, if anything this will hurt any hype people would have for the game.
I'd rather game developers just wait until it's actually decent to look at and not when it's only in pre-alpha.
At least with Star Fox being shown off early I can kinda understand since Nintendo is trying to get people excited about the Wii U's future, but this?
No real point in it.
EDIT: Also, developers of UCraft. That's a big hype killer too.
