I think the Deathmatch has justified the gaming community's admiration for this game.
A lot of game awards like the 'VGA's are said to be based on how well they sell and the choices are pretty biased which just lowers the respectability for this event; it means nothing. There's nothing to get worked over award events like these.
When it comes to 'peoples choice awards' it has so much more value. And if Skyward Sword wins in any of them, I would be happy enough. It shows that the community has taste and knows a great game when they see one. I would think that Nintendo will be pleased if they knew that such a majority has noticed such a masterpiece that they've worked so hard on.
Considering the gaming industry today, with the appeal going toward generic gritty games, FPS and all that Hardcore stuff, Skyward Sword had some competition-- but it won because the audience loved it, and that's all that matters.
