What i don't understand: Why would 1up jump to such conclusions? They have experienced writers on their staff and surley they all know that every prime game was demoed with action packed segments.
I'm not gonna attack 1up or anything because I enjoy a lot of their games coverage, but this seems extremly premature, especially looking at the history of the franchise and what the developers have said about this game. They've gone out of their way to say that it's an adventure game first and does contain all the elements that make a metroid game unique.
Also, the sky town segment has nothing in common with Halo. The general lack of combat in that demo and the rich art on display all reminded me of the other prime games in a big way.
So yeah, I haven't played the game, and they have, but I've watched a ton of videos and I just don't see what they're talking about, nor do I see any reason to doubt retro's promises about the overall content of the game.
