I don't think any of those selections really deserve it, I suspect the key point might be "membership in the writer's guild".
Uncharted 2 is pretty much every action Clique ever unleashed, Wet is the same thing channeling Quentin Tarantino with a protaganist that seems to be universally reviled by gamers despite being a hot babe (and honestly when you consider how gamers quintenseentially react to our video game babes that says a lot), Wolverine must have seen a lot of bribe money passed out becase it has a ton of nominations when the best thing most gamers say about it is "better than the movie" which given the treatment of fan favorites like Deadpool and it's general reception is sort of like saying "better than maggots crawling in road kill".
The award might be respected by the industry for whatever reason, but right now this selection doesn't give it any cred with me, and going by the responses I hardly seem to be alone.
All that's missing is for them to nominate Mario for great writing... that would make the sell out complete.
